* On squeeze, use release fact instead of hardcoded release name
* On wheezy, special-case because codename selector is not available
* On jessie and up, start pulling in point-release updates. The
codename selector ensures that we won't be upgrading to a new
release automatically.
* Removes dependency on lsb-release and/or Facter >1.7
(values are based on $::lsbdistcodename, when available)
* Simplifies maintenance: only lib/facter/util/* require updates as new
releases are made
Caveats:
* apt::codename is removed; to override debian_* facts, set the
FACTER_debian_codename environment variable for puppet
* If tracking unstable, make sure lsb-release is installed, as other
methods can't tell between testing and unstable
This functionality was lost because we stopped using a source file for
the 50unattended-upgrades file that would previously let one override
the configuration per release or per host.
with the release of squeeze-lts, the current way we deal with security
sources is problemaic. by flipping things around we hope to make the
files contents more stable.
What happened here was the $codename = $::lsbdistcodename was removed from
init.pp and replaced with just $::lsbdistcodename whereever $codename was
used. Then in the sources.list.erb and preferences files things were changed
like this:
<pre>+### Debian current: <%= codename = scope.lookupvar('::lsbdistcodename') %>
...
-deb <%= debian_url %> <%= codename %> <%= repos %>
...
+deb <%= debian_url=scope.lookupvar('apt::debian_url') %> <%= codename %> <%= repos=scope.lookupvar('apt::repos') %>
</pre>
This meant that the codename was always set to lsbdistcodename, and you because
in newer puppet versions you cannot assign a value to a top-level facter
variable, it is not possible to change this.
Because we cannot change $lsbdistcodename, we have to fix this by allowing the
user to pass a different, non-top-level scoped variable to the class as a
parameter, which defaults to $::lsbdistcodename, so that upgrades can be
triggered.
This is documented in the README in an upgrade notice
This is implemented by adding a "package" parameter to apt::preferences_snippet,
so that define names can be kept unique while the package names are
not necessarily.
Closes: Redmine#3468.
