Subject: [PATCH 2/3] Don't unnecessarily try to change a file context
|
||||
|
||||
As pointed out by Tim Waugh here:
|
||||
|
||||
https://bugzilla.redhat.com/507555
|
||||
|
||||
We shouldn't bother trying to set the context of a file if it already
|
||||
matches what we want.
|
||||
|
||||
(Fixed to use STREQ() and not use tabs, as pointed out by danpb)
