I can take a look on Friday hopefully.

Here's an example manifest, store in `11988_symlink.pp`:
augeas { "11988_symlink":
root => "/tmp/symlink",
context => "/files/etc/grub.conf",
changes => "set timeout 2",
}
And then to reproduce it:
$ mkdir -p /tmp/symlink/etc
$ echo "timeout 5" > /tmp/symlink/realgrub.conf
$ ln -s ../realgrub.conf /tmp/symlink/etc/grub.conf
$ puppet apply 11988_symlink.pp

$ ls -l /tmp/symlink/*

Bug #11988: Augeas provider can clobber symlinks
https://projects.puppetlabs.com/issues/11988
Author: Nathan Huff
Status: Accepted
Priority: Normal
Assignee: Dominic Cleal
Category: augeas
Target version: 2.7.x
Affected Puppet version: 2.7.9
Keywords: augeas
Branch:
If the augeas resource is fed a symlink as the target file and it
makes changes it will overwrite it with a regular file. It creates
and .augnew file and just blindly moves it into place without checking
if the target file was a symlink.
The provider should either check whether the target was a symlink and
dereference it or it should rerun augeas in overwrite mode since augeas does
take care to dereference if necessary.
