property-based host configuration management in haskell

Latest on Hackage:4.0.2

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

Propellor is a configuration management system using Haskell and Git. Each system has a list of properties, which Propellor ensures are satisfied. Linux and FreeBSD are supported.

Propellor is configured via a git repository, which typically lives in ~/.propellor/ on your development machine. Propellor clones the repository to each host it manages, in a secure way. See components for details.

Properties are defined using Haskell in the file ~/.propellor/config.hs. There is fairly complete API documentation, which includes many built-in Properties for dealing with Apt and Apache , Cron and Commands , Dns and Docker, etc.

There is no special language as used in puppet, chef, ansible, etc.. just the full power of Haskell. Hopefully that power can be put to good use in making declarative properties that are powerful, nicely idempotent, and easy to adapt to a system's special needs!

If using Haskell to configure Propellor seems intimidating, see configuration for the Haskell newbie.

quick start

  1. Get propellor installed on your development machine (ie, laptop). cabal install propellor or apt-get install propellor
  2. Run propellor --init ; this will set up a ~/.propellor/ git repository for you.
  3. Edit ~/.propellor/config.hs, and add a host you want to manage. You can start by not adding any properties, or only a few.
  4. Run: propellor --spin $HOST
  5. Now you have a simple propellor deployment to a host. Continue editing ~/.propellor/config.hs to further configure the host, add more hosts etc, and re-run propellor --spin $HOST after each change.
  6. Once you have a lot of hosts, and running propellor --spin HOST for each host becomes tiresome, you can automate that.
  7. Write some neat new properties and send patches!


propellor (4.0.2) unstable; urgency=medium

* Apt.mirror can be used to set the preferred apt mirror of a host,
overriding the default CDN. This info is used by
Apt.stdSourcesList and Sbuild.builtFor.
Thanks, Sean Whitton.
* Property.Partition: Update kpartx output parser, as its output format
changed around version 0.6. Both output formats are supported now.
* Fix bug when using setContainerProps with a chroot that prevented
properties added to a chroot that way from being seen when propellor
was running inside the chroot. This affected disk image creation, and
possibly other things that use chroots.

* Tor.named, Tor.torPrivKey: Include the new ed25519 public/private key
pair in addition to the old secret_id_key.

propellor (4.0.0) unstable; urgency=medium

* Added Monoid instances for Property and RevertableProperty.
* Removed applyToList. Instead, use mconcat. (API change)
If you had: applyToList accountFor [User "joey", User "root"]
use instead: mconcat (map accountFor [User "joey", User "root"])
* Makefile: Removed "run" target which was default target.
"make" now only builds propellor, does not run it.
Note that propellor 1.0.0 and earlier relied on this target for
the Cron.runPropellor property's cronjob to work, so upgrading
directly from 1.0.0 to 4.0.0 would break that cron job.
* Remove make from propellor's dependency list; it's not used by
propellor any longer.
* Implemented hostChroot, as originally seen in my slides at
Linux.Conf.Au 2017 in January. Now that it's not vaporware, it allows
one Host to build a disk image that has all the properties of another
* DiskImage building properties used to propagate DNS info out from
the chroot used to build the disk image to the Host. That is no longer
done, since that chroot only exists as a side effect of the disk image
creation and servers will not be running in it.
* The IsInfo types class's propagateInfo function changed to use a
PropagateInfo data type. (API change)
* The action used to satisfy a property changed to Maybe (Propellor Result).
When it is Nothing, propellor knows it can skip displaying the
description of that property. This is mostly useful in the
implementation of mempty. (API change)
* The doNothing property is now simply mempty. The name was retained
because it can be clearer than mempty in some contexts.
* Added Apache.confEnabled.

propellor (3.4.0) unstable; urgency=medium

* Added ConfigurableValue type class, for values that can be used in a
config file, or to otherwise configure a program.
* The val function converts such values to String.
* Removed fromPort and fromIPAddr (use val instead). (API change)
* Removed several Show instances that were only used for generating
configuration, replacing with ConfigurableValue instances. (API change)
* The github mirror of propellor's git repository has been removed,
since github's terms of service has started imposing unwanted licensing
* propellor --init: The option to clone propellor's git repository
used to use the github mirror, and has been changed to use a different

propellor (3.3.0) unstable; urgency=medium

* Arch Linux is now supported by Propellor!
Thanks to Zihao Wang for this port.
* Added Propellor.Property.Pacman for Arch's package manager.
Maintained by Zihao Wang.
* The types of some properties changed; eg from Property DebianLike
to Property (DebianLike + ArchLinux). Also, DebianLike and Linux
are no longer type synonyms; propellor now knows that Linux includes
ArchLinux. This could require updates to code, so is a minor API change.
* GHC's fileSystemEncoding is used for all String IO, to avoid
encoding-related crashes in eg, Propellor.Property.File.
* Add --build option to simply build config.hs.
* More informative usage message. Thanks, Daniel Brooks
* Tor.hiddenService' added to support multiple ports.
Thanks, Félix Sipma.
* Apt.noPDiffs added.
Thanks, Sean Whitton.
* stack.yaml: Compile with GHC 8.0.1 against lts-7.16.
Thanks, Andrew Cowie.
* Added Propellor.Property.File.configFileName and related functions
to generate good filenames for config directories.
* Added Apt.suiteAvailablePinned, Apt.pinnedTo.
Thanks, Sean Whitton.
* Added File.containsBlock

[ Sean Whitton ]
* Using ccache with Sbuild.built & Sbuild.builtFor is now toggleable: these
properties now take a parameter of type Sbuild.UseCcache. (API Change)
* Sbuild.piupartsConf: no longer takes an Apt.Url. (API Change)
* Sbuild.piupartsConf & Sbuild.piupartsConfFor: does nothing if corresponding
schroot not built.
Previously, these properties built the schroot if it was missing.
* Sbuild.built & Sbuild.piupartsConf: add an additional alias to sid chroots.
This is for compatibility with `dgit sbuild`.
* Further improvements to Sbuild.hs haddock.

[ Joey Hess ]
* Tor.hiddenService: Converted port parameter from Int to Port. (API change)
* Tor.hiddenServiceAvailable: The hidden service hostname file may not
be available immedaitely after configuring tor; avoid ugly error in
this case.

[ Joey Hess ]
* Ssh.knownHost: Bug fix: Only fix up the owner of the known_hosts
file after it exists.

[ Sean Whitton ]
* Sbuild.keypairInsecurelyGenerated: Improved to be more robust.
* Pass --allow-unrelated-histories to git merge when run with git 2.9 or
newer. This fixes the /usr/bin/propellor wrapper with this version of git.
* Sbuild.built & Sbuild.builtFor no longer require Sbuild.keypairGenerated.
Transition guide: If you are using sbuild 0.70.0 or newer, you should
`rm -r /var/lib/sbuild/apt-keys`. Otherwise, you should add either
Sbuild.keypairGenerated or Sbuild.keypairInsecurelyGenerated to your host.
* Sbuild haddock improvements:
- State that we don't support squeeze and Buntish older than trusty.
This is due to our enhancements, such as eatmydata.
- State that you need sbuild 0.70.0 or newer to build for stretch.
This is due to gpg2 hitting Debian stretch.
- Explain when a keygen is required.
- Update sample ~/.sbuildrc for sbuild 0.71.0.
- Add hint for customising chroots with propellor.
- Update example usage of System type.

* Architecture changed from String to an ADT. (API Change)
Transition guide: Change "amd64" to X86_64, "i386" to X86_32,
"armel" to ARMEL, etc.
Thanks, Félix Sipma.
* The Debian data type now includes a DebianKernel. (API Change)
This won't affect most config.hs, as osDebian defaults to
Linux. Added osDebian' can be used to specify a different kernel.
Thanks, Félix Sipma.
* Improve exception handling. A property that threw a non-IOException
used to stop the whole propellor run. Now, all non-async exceptions
only make the property that threw them fail. (Implicit API change)
* Added StopPropellorException and stopPropellorMessage which can be
used in the unusual case where a failure of one property should stop
propellor from trying to ensure any other properties.
* tryPropellor returns Either SomeException instead of Either IOException
(API change)
* Switch letsencrypt to certbot package name.
* Sbuild: Add keyringInsecurelyGenerated which is useful on throwaway
build VMs.
Thanks, Sean Whitton
* Added Propellor.Property.SiteSpecific.Exoscale.
Thanks, Sean Whitton
* Property.Reboot: Added toDistroKernel and toKernelNewerThan.
Thanks, Sean Whitton
* Added ConfFile.hasIniSection.
Thanks, Félix Sipma.
* Apt.install: When asked to install a package that apt does not know
about, it used to incorrectly succeed. Now it will fail.
* Property.Firejail: New module.
Thanks, Sean Whitton
* File: Write privdata files in binary rather than text, which avoids
failure when they do not contain valid unicode.
Thanks, Andrew Schurman
* Generalized fileProperty can now operate on a file as either a series
of lines, or a ByteString.

[ Sean Whitton ]
* New info property Schroot.useOverlays to indicate whether you want schroots
set up by propellor to use the Linux kernel's OverlayFS.
* Schroot.overlaysInTmpfs sets Schroot.useOverlays info property.
* If you have indicated that you want schroots to use OverlayFS and the
current kernel does not support it, Sbuild.built will attempt to reboot
into a kernel that does, or fail if it can't find one.
* Sbuild.built will no longer add duplicate `aliases=UNRELEASED,sid...` lines
to more than one schroot config. It will not remove any such lines that the
previous version of propellor added, though.
* Sbuild.keypairGenerated works around Debian bug #792100 by creating the
directory /root/.gnupg in advance.
* Ccache.hasCache now sets the setgid bit on the cache directory, as
ccache requires.

propellor (3.0.0) unstable; urgency=medium

* Property types have been improved to indicate what systems they target.
This prevents using eg, Property FreeBSD on a Debian system.
Transition guide for this sweeping API change:
- First, upgrade to propellor 2.17.2 and deploy that to all your hosts.
Otherwise, propellor --spin will fail when you upgrade to
propellor 3.0.0.
- Change "host name & foo & bar"
to "host name $ props & foo & bar"
- Similarly, `propertyList` and `combineProperties` need `props`
to be used to combine together properties; they no longer accept
lists of properties. (If you have such a list, use `toProps`.)
- And similarly, Chroot, Docker, and Systemd container need `props`
to be used to combine together the properies used inside them.
- The `os` property is removed. Instead use `osDebian`, `osBuntish`,
or `osFreeBSD`. These tell the type checker the target OS of a host.
- Change "Property NoInfo" to "Property UnixLike"
- Change "Property HasInfo" to "Property (HasInfo + UnixLike)"
- Change "RevertableProperty NoInfo" to
"RevertableProperty UnixLike UnixLike"
- Change "RevertableProperty HasInfo" to
"RevertableProperty (HasInfo + UnixLike) UnixLike"
- GHC needs {-# LANGUAGE TypeOperators #-} to use these fancy types.
This is enabled by default for all modules in propellor.cabal. But
if you are using propellor as a library, you may need to enable it
- If you know a property only works on a particular OS, like Debian
or FreeBSD, use that instead of "UnixLike". For example:
"Property Debian"
- It's also possible make a property support a set of OS's, for example:
"Property (Debian + FreeBSD)"
- Removed `infoProperty` and `simpleProperty` constructors, instead use
`property` to construct a Property.
- Due to the polymorphic type returned by `property`, additional type
signatures tend to be needed when using it. For example, this will
fail to type check, because the type checker cannot guess what type
you intend the intermediate property "go" to have:
foo :: Property UnixLike
foo = go `requires` bar
go = property "foo" (return NoChange)
To fix, specify the type of go:
go :: Property UnixLike
- `ensureProperty` now needs to be passed a witness to the type of the
property it's used in.
change this: foo = property desc $ ... ensureProperty bar
to this: foo = property' desc $ \w -> ... ensureProperty w bar
- General purpose properties like cmdProperty have type "Property UnixLike".
When using that to run a command only available on Debian, you can
tighten the type to only the OS that your more specific property works on.
For example:
upgraded :: Property Debian
upgraded = tightenTargets (cmdProperty "apt-get" ["upgrade"])
- Several utility functions have been renamed:
getInfo to fromInfo
propertyInfo to getInfo
propertyDesc to getDesc
propertyChildren to getChildren
* The new `pickOS` property combinator can be used to combine different
properties, supporting different OS's, into one Property that chooses
which to use based on the Host's OS.
* Re-enabled -O0 in propellor.cabal to reign in ghc's memory use handling
these complex new types.
* Added dependency on concurrent-output; removed embedded copy.
* Apt.PPA: New module, contributed by Evan Cofsky.
* Improved propellor's first run experience; propellor --init will
walk the user through setting up ~/.propellor, with a choice between
a clone of propellor's git repository, or a minimal config, and will
configure propellor to use a gpg key.
* Stack support. "git config propellor.buildsystem stack" will make
propellor build its config using stack.
* When propellor is installed using stack, propellor --init will
automatically set propellor.buildsystem=stack.

-- Joey Hess <> Sat, 02 Apr 2016 15:33:26 -0400

propellor (2.17.2) unstable; urgency=medium

* When new dependencies are added to propellor or the propellor config,
try harder to get them installed. In particular, this makes
propellor --spin work when the remote host needs to get dependencies
installed in order to build the updated config.
* Apt.update: Also run dpkg --configure -a here as apt for some reason
won't even update if dpkg was interrupted.

propellor (2.17.1) unstable; urgency=medium

* Avoid generating excessively long paths to the unix socket file
used for ssh connection caching. Mostly. Can still generate a too long
one if $HOME is longer than 60 bytes.
* Uwsgi: add ".ini" extension to app config files.
Files without extensions were ignored by uwsgi.
Thanks, Félix Sipma.

* Firewall: add TCPFlag, Frequency, TCPSyn, ICMPTypeMatch, NatDestination
Thanks, Félix Sipma.
* Network: Filter out characters not allowed in interfaces.d files.
Thanks, Félix Sipma.
* Apt.upgrade: Run dpkg --configure -a first, to recover from
interrupted upgrades.
* Apt: Add safeupgrade.
* Force ssh, scp, and git commands to be run in the foreground.
Should fix intermittent hangs of propellor --spin.
* Avoid repeated re-building on systems such as FreeBSD where building
re-links the binary even when there are no changes.
* Locale.available: Run locale-gen, instead of dpkg-reconfigure locales,
which modified the locale.gen file and sometimes caused the property to
need to make changes every time.
* Speed up propellor's build of itself, by asking cabal to only build
the propellor-config binary and not all the libraries.
* Tor.named: Fix bug that sometimes caused the property to fail the first
time, though retrying succeeded.

scarce resources (particularly memory). Other jobs block on a lock
* Removed references to a Debian derivative from code and documentation
because of an unfortunate trademark use policy.
* That included changing a data constructor to "Buntish", an API change.
* Firewall.rule: Now takes a Table parameter. (API change)

propellor (2.15.0) unstable; urgency=medium

* Added UncheckedProperty type, along with unchecked to indicate a
Property needs its result checked, and checkResult and changesFile
to check for changes.
* Properties that run an arbitrary command, such as cmdProperty
and scriptProperty are converted to use UncheckedProperty, since
they cannot tell on their own if the command truely made a change or not.
(API Change)
Transition guide:
- When GHC complains about an UncheckedProperty, add:
`assume` MadeChange
(Since these properties used to always return MadeChange, that
change is always safe to make.)
- Or, if you know that the command should modifiy a file, use:
`changesFile` filename
* The `trivial` combinator has been removed. (API change)
Instead, use:
`assume` NoChange
Or, better, use changesFile or checkResult to accurately report
when a property makes a change.
* A few properties have had their Result improved, for example
Apt.buldDep and Apt.autoRemove now check if a change was made or not.
* User.hasDesktopGroups changed to avoid trying to add the user to
groups that don't exist.
* Added Postfix.saslPasswdSet.
* Added Propellor.Property.Locale.

propellor (2.13.0) unstable; urgency=medium

* RevertableProperty used to be assumed to contain info, but this is
now made explicit, with RevertableProperty HasInfo or
RevertableProperty NoInfo. (API change)
Transition guide:
- If you define a RevertableProperty, expect some type check
failures like: "Expecting one more argument to ‘RevertableProperty’".
- Change it to "RevertableProperty NoInfo"
- The compiler will then tell you if it needs "HasInfo" instead.
- If you have code that uses the RevertableProperty constructor
that fails to type check, use the more powerful <!> operator
instead to create the RevertableProperty.
* Various property combinators that combined a RevertableProperty
with a non-revertable property used to yield a RevertableProperty.
This was a bug, because the combined property could not be fully
reverted in many cases, and the result is now a non-revertable property.
* combineWith now takes an additional parameter to control how revert
actions are combined (API change).
* Added Propellor.Property.Concurrent for concurrent properties.
* Made the execProcess exported by propellor, and everything built on it,
avoid scrambled output when run concurrently.
* Propellor now depends on STM and text.
* The cabal file now builds propellor with -O. While -O0 makes ghc
take less memory while building propellor, it can lead to bad memory
usage at runtime due to eg, disabled stream fusion.

* Added Mount.fstabbed property to generate /etc/fstab to replicate
current mounts.
* HostName: Improve domain extraction code.
* Add File.basedOn. Thanks, Per Olofsson.
* Changed how the operating system is provided to Chroot (API change).
Where before debootstrapped and bootstrapped took a System parameter,
the os property should now be added to the Chroot.
* Follow-on change to Systemd.container, which now takes a System parameter.
* Generalized Property.check so it can be used with Propellor actions as
well as IO actions.
* Hostname.sane and Hostname.setTo can now safely be used as a property
of a chroot, and won't affect the hostname of the host system.

propellor (2.9.0) unstable; urgency=medium

* Added basic Uwsgi module, maintained by Félix Sipma.
* Add Apt.hasForeignArch. Thanks, Per Olofsson.
* Improved documentation, particularly of the Propellor module.
* The Propellor module no longer exports many of the things it used to,
being now focused on only what's needed to write config.hs.
Use Propellor.Base to get all the things exported by Propellor before.
(API change)
* Some renaming of instance methods, and moving of functions to more
appropriate modules. (API change)
* Added File.isSymlinkedTo. Thanks, Per Olofsson.
* fileProperty, and properties derived from it now write the new
file content via origfile.propellor-new~, instead of to a randomly named
temp file. This allows them to clean up any temp file that may have
been left by an interrupted run of propellor.
* Added Propellor.Property.Spin, which can be used to make a host be a
controller of other hosts, which will automatically spin them each time
propellor is run.
* Ssh.keyImported is replaced with Ssh.userKeys. (API change)
The new property only gets the private key from the privdata; the
public key is provided as a parameter, and so is available as
Info that other properties can use.
* Ssh.keyImported' is renamed to Ssh.userKeyAt, and also changed
to only import the private key from the privdata. (API change)
* While Ssh.keyImported and Ssh.keyImported' avoided updating existing
keys, the new Ssh.userKeys and Ssh.userKeyAt properties will
always update out of date key files.
* Ssh.pubKey renamed to Ssh.hostPubKey. (API change)
* Added --unset-unused
* Fix typo: propigate → propagate. Thanks, Felix Gruber.
(A minor API change)
* Chroot: Converted to use a ChrootBootstrapper type class, so
other ways to bootstrap chroots can easily be added in separate
modules. (API change)

propellor (2.8.1) unstable; urgency=medium

* Guard against power loss etc when building propellor, by updating
the executable atomically.
* Added Logcheck module, contributed by Jelmer Vernooij.
* Added Kerberos module, contributed by Jelmer Vernooij.
* Privdata that uses HostContext inside a container will now have the
name of the container as its context, rather than the name of
the host(s) where the container is used. This allows eg, having different
passwords for a user in different containers. Note that previously,
propellor would prompt using the container name as the context, but
not actually use privdata using that context; so this is a bug fix.
* Fix --add-key to not fail committing when no privdata file exists yet.

propellor (2.8.0) unstable; urgency=medium

* Added Propellor.Property.Rsync.

info of any type that is Typeable and a Monoid, including data types
private to a module. (API change)
Thanks to Joachim Breitner for the idea.
* Improve propellor wrapper to better handle installation cloning
the public propellor repo, by setting that repo to be upstream,
so propellor doesnt try to push to a read-only repo.
* Added DebianMirror module, contributed by Félix Sipma.
* Some hlint cleanups.
Thanks, Mario Lang
* Added Propellor.Property.Unbound for the caching DNS server.
Thanks, Félix Sipma.
* Added PTR to Dns.Record. While this is ignored by
Propellor.Property.Dns for now, since reverse DNS setup is not
implemented there yet, it can be used in other places, eg Unbound.
Thanks, Félix Sipma.
* PrivData converted to newtype (API change).
* Stopped stripping trailing newlines when setting PrivData;
this was previously done to avoid mistakes when pasting eg passwords
with an unwanted newline. Instead, PrivData consumers should use either
privDataLines or privDataVal, to extract respectively lines or a
value (without internal newlines) from PrivData.
* Allow storing arbitrary ByteStrings in PrivData, extracted using

more generic cmdProperty' (API change)
* Add docker image related properties.
Thanks, Antoine Eiche.
* Export CommandParam, boolSystem, safeSystem, shellEscape, and
createProcess from Propellor.Property.Cmd, so they are available
for use in constricting your own Properties when using propellor
as a library.
* Improve enter-machine scripts for systemd-nspawn containers to unset most
environment variables.
* Fix Postfix.satellite bug; the default relayhost was set to the
domain, not to smtp.domain as documented.
* Mount /proc inside a chroot before provisioning it, to work around #787227
* --spin now works when given a short hostname that only resolves to an
ipv6 address.
* Added publish property for systemd-spawn containers, for port publishing.
(Needs systemd version 220.)
* Added bind and bindRo properties for systemd-spawn containers.
* Firewall: Port was changed to a newtype, and the Port and PortRange
constructors of Rules were changed to DPort and DportRange, respectively.
(API change)
* Docker: volume and publish accept Bound FilePath and Bound Port,
respectively. They also continue to accept Strings, for backwards

* Git.bareRepo: Fix bug in calls to userScriptProperty.
Thanks, Jelmer Vernooij.
* Removed Obnam.latestVersion which was only needed for Debian wheezy
* Merged Utility changes from git-annex.
* Switched from MonadCatchIO-transformers to the newer transformers and
exceptions libraries.
* Ensure build deps are installed before building propellor in --spin

propellor (2.3.0) unstable; urgency=medium

* Make propellor resistent to changes to shared libraries, such as libffi,
which might render the propellor binary unable to run. This is dealt with
by checking the binary both when running propellor on a remote host,
and by Cron.runPropellor. If the binary doesn't work, it will be rebuilt.
* Note that since a new switch had to be added to allow testing the binary,
upgrading to this version will cause a rebuild from scratch of propellor.
* Added hasLoginShell and shellEnabled.
* debCdn changed to new official replacement for

propellor (2.0.0) unstable; urgency=medium

* Property has been converted to a GADT, and will be Property NoInfo
or Property HasInfo.
This was done to make sure that ensureProperty is only used on
properties that do not have Info.
Transition guide:
- Change all "Property" to "Property NoInfo" or "Property HasInfo"
(The compiler can tell you if you got it wrong!)
- To construct a RevertableProperty, it is useful to use the new
(<!>) operator
- Constructing a list of properties can be problimatic, since
Property NoInto and Property HasInfo are different types and cannot
appear in the same list. To deal with this, "props" has been added,
and can built up a list of properties of different types,
using the same (&) and (!) operators that are used to build
up a host's properties.
* Add descriptions of how to set missing fields to --list-fields output.
* Properties now form a tree, instead of the flat list used before.
This includes the properties used inside a container.
* Fix info propagation from fallback combinator's second Property.
* Added systemd configuration properties.
* Added journald configuration properties.
* Added more network interface configuration properties.
* Implemented OS.preserveNetwork.

propellor (1.1.0) unstable; urgency=medium

* --spin target --via relay causes propellor to bounce through an
intermediate relay host, which handles any necessary uploads
when provisioning the target host.
* --spin can be passed multiple hosts, and it will provision each host
in turn.
* Add --merge, to combine multiple --spin commits into a single, more useful
* Hostname parameters not containing dots are looked up in the DNS to
find the full hostname.
* propellor --spin can now deploy propellor to hosts that do not have
git, ghc, or apt-get. This is accomplished by uploading a fairly
portable precompiled tarball of propellor.
* Propellor.Property.OS contains properties that can be used to do a clean
reinstall of the OS of an existing host. This can be used, for example,
to do an in-place conversion from Fedora to Debian.
This is experimental; use with caution!
* Added group-related properties. Thanks, Félix Sipma.
* Added Git.barerepo. Thanks, Félix Sipma.
* Added Grub.installed and properties.
* New HostContext can be specified when a PrivData value varies per host.
* hasSomePassword and hasPassword now default to using HostContext.
To specify a different context, use hasSomePassword' and
hasPassword' (API change)
* hasSomePassword and hasPassword now make sure shadow passwords are enabled.
* cron.runPropellor now runs propellor, rather than using its Makefile.
This is more robust.
* propellor.debug can be set in the git config to enable more persistent
debugging output.
* Run apt-cache policy with LANG=C so it works on other locales.
* endAction can be used to register an action to run once propellor
has successfully run on a host.

propellor (1.0.0) unstable; urgency=medium

* propellor --spin can now be used to update remote hosts, without
any central git repository needed. The central git repository is
still useful for running propellor from cron, but this simplifies
getting started with propellor, and allows for more ad-hoc usage.
* The git repo url, if any, is updated whenever propellor --spin is used.
* Added prosody module, contributed by Félix Sipma.
* Can be used to configure tor hidden services. Thanks, Félix Sipma.
* When multiple gpg keys are added, ensure that the privdata file

* Convert GpgKeyId to newtype. (API change)
* DigitalOcean.distroKernel property now reboots into the distribution
kernel when necessary.
* Avoid outputting color setting sequences when not run on a terminal.
* Docker code simplified by using `docker exec`; needs docker 1.3.1.

in the main host list, and are instead passed to
Docker.docked. (API change)
* Added support for using debootstrap from propellor.
* Propellor can now be used to provision chroots.
* systemd-nspawn containers can now be managed by propellor, very similar

* Avoid encoding the current stable suite in propellor's code,
since that poses a difficult transition around the release,
and can easily be wrong if an older version of propellor is used.
Instead, the os property for a stable system includes the suite name
to use, eg Stable "wheezy".
* stdSourcesList uses the stable suite name, to avoid unwanted
immediate upgrades to the next stable release. (API change)

propellor (0.8.0) unstable; urgency=medium

* Completely reworked privdata storage. There is now a single file,
and each host is sent only the privdata that its Properties actually use.

To transition existing privdata, run propellor against a host and
watch out for the red failure messages, and run the suggested commands
to store the privdata using the new storage scheme. You may find
it useful to run the old version of propellor to extract data from the old
privdata files during this migration.

Several properties that use privdata now require a context to be
specified. If in doubt, you can use anyContext, or
Context ""

* Add --edit to edit a privdata value in $EDITOR.
* Add --list-fields to list all currently set privdata fields, along with
the hosts that use them.
* Fix randomHostKeys property to run openssh-server's postinst in a
non-failing way.
* Hostname.sane now cleans up the localhost line in /etc/hosts,

propellor (0.2.2) unstable; urgency=medium

* Now supports provisioning docker containers with architecture/libraries
that do not match the host.
* Fixed a bug that caused file modes to be set to 600 when propellor
modified the file (did not affect newly created files).

propellor (0.2.0) unstable; urgency=low

* Added support for provisioning Docker containers.
* Bootstrap deployment now pushes the git repo to the remote host
over ssh, securely.
* propellor --add-key configures a gpg key, and makes propellor refuse
to pull commits from git repositories not signed with that key.
This allows propellor to be securely used with public, non-encrypted
git repositories without the possibility of MITM.
* Added support for type-safe reversions. Only some properties can be
reverted; the type checker will tell you if you try something that won't
* New syntactic sugar for building a list of properties, including
revertable properties.
