delimited string using the `packages` attribute or pass in an array of package
names.
+### apt::hold
+
+When you wish to hold a package in Puppet is should be done by passing in
+'held' as the ensure attribute to the package resource. However, a lot of
+public modules do not take this into account and generally do not work well
+with an ensure of 'held'.
+
+There is an additional issue that when Puppet is told to hold a package, it
+will hold it at the current version installed, there is no way to tell it in
+one go to install a specific version and then hold that version without using
+an exec resource that wraps `dpkg --set-selections` or `apt-mark`.
+
+At first glance this could also be solved by just passing the version required
+to the ensure attribute but that only means that Puppet will install that
+version once it processes that package. It does not inform apt that we want
+this package to be held. In other words; if another package somehow wants to
+upgrade this one (because of a version requirement in a dependency), apt
+should not allow it.
+
+In order to solve this you can use apt::hold. It's implemented by creating
+a preferences file with a priority of 1001, meaning that under normal
+circumstances this preference will always win. Because the priority is > 1000
+apt will interpret this as 'this should be the version installed and I am
+allowed to downgrade the current package if needed'.
+
+With this you can now set a package's ensure attribute to 'latest' but still
+get the version specified by apt::hold. You can do it like this:
+
+ apt::hold { 'vim':
+ version => '2:7.3.547-7',
+ }
+
+Since you might just want to hold Vim at version 7.3 and not care about the
+rest you can also pass in a version with a glob:
+
+ apt::hold { 'vim':
+ version => '2:7.3.*',
+ }
+
### apt::ppa
Adds a ppa repository using `add-apt-repository`.
key_server => 'pgp.mit.edu',
}
+
+#### Hiera example
+<pre>
+apt::sources:
+ 'debian_unstable':
+ location: 'http://debian.mirror.iweb.ca/debian/'
+ release: 'unstable'
+ repos: 'main contrib non-free'
+ required_packages: 'debian-keyring debian-archive-keyring'
+ key: '55BE302B'
+ key_server: 'subkeys.pgp.net'
+ pin: '-10'
+ include_src: 'true'
+
+ 'puppetlabs':
+ location: 'http://apt.puppetlabs.com'
+ repos: 'main'
+ key: '4BD6EC30'
+ key_server: 'pgp.mit.edu'
+</pre>
+
### Testing
The APT module is mostly a collection of defined resource types, which provide reusable logic that can be leveraged to manage APT. It does provide smoke tests for testing functionality on a target system, as well as spec tests for checking a compiled catalog against an expected set of resources.
Adds the necessary components to get backports for Ubuntu and Debian. The release name defaults to `$lsbdistcodename`. Setting this manually can cause undefined behavior (read: universe exploding).
+By default this class drops a Pin-file for Backports pinning it to a priority of 200, lower than the normal Debian archive which gets a priority of 500 to ensure your packages with `ensure => latest` don't get magically upgraded from Backports without your explicit say-so.
+
+If you raise the priority through the `pin_priority` parameter to *500*, identical to the rest of the Debian mirrors, normal policy goes into effect and the newest version wins/becomes the candidate apt will want to install or upgrade to. This means that if a package is available from Backports it and its dependencies will be pulled in from Backports unless you explicitly set the `ensure` attribute of the `package` resource to `installed`/`present` or a specific version.
