[Bug 1328677] Re: unity first-run stamp should not be in XDG_CACHE_HOME

 

Attached debdiff between trusty-updates and SRU.

** Branch unlinked: lp:~unity-team/unity/trusty-1328677

** Patch added: "debdiff between unity_7.2.3+14.04.20140826-0ubuntu1 and unity_7.2.4+14.04.20141217-0ubuntu1"
   https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1328677/+attachment/4289426/+files/unity_7.2.4%2B14.04.20141217-0ubuntu1.debdiff

** Description changed:

+ [ Impact ]
+ 
  The unity first_run.stamp file should not be in XDG_CACHE_HOME.  As it
  is a _cache_, it can be ephemeral.  Rather, it should be in
  XDG_CONFIG_HOME.  Once the keyboard shortcut list, for example, has been
  presented, I don't need to be told about it again, even if I need to
  purge my ~/.cache directory.
  
  This is a problem at our site, where XDG_CACHE_HOME is stored on a
  temporary filesystem, to cut down on the tremendous amount of useless
  network traffic between workstations and the user's file server.  As a
  result, users now have to learn about Unity keyboard shortcuts on every
  single login.
