I noticed this behaviour because $::debian_nextcodename was
"squeeze" on a wheezy host.
For debugging, i inserted a "puts codenames" in
lib/facter/debian_nextcodename.rb, and it turned out that it
was sorted differently on wheezy and jessie hosts:
On wheezy:
buster
stretch
jessie
wheezy
squeeze
lenny
On jessie:
lenny
squeeze
wheezy
jessie
stretch
buster
So i decided to rewrite this so this doesn't happen again.
requirering the facter/util/debian.rb module causes
puppet warnings on wheezy hosts, and custom facts like
`$::debian_codename` cannot be evaluated.
warning: Could not load fact file
/srv/dev/projects/puppet/shared-modules//apt/lib/facter/debian_nextcodename.rb:
no such file to load -- facter/util/debian
Removing the require line solves this.
* 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
