Issue #11988 has been updated by Jeff McCune.

# Update on save_mode #

Unfortunately the needs_to_run method currently has the behavior of producing a 
`*.augnew` file for each file being managed by Augeas.  This side effect is 
relied upon by the `sync` method of the `returns` property in the augeas type.  
In order to implement the strategy Dominic proposed of using the SAVE_BACKUP 
augeas mode I believe we need to significantly refactor the augeas provider to 
avoid this side effect and instead implement a more direct method of 
implementing the type's `retrieve` and `sync` methods.

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.
