Subject: Several fixes to restorecond
Date: Tue, 17 Feb 2009 11:40:54 -0500	[thread overview]
Message-ID: <499AE896.8000709@redhat.com> (raw)

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Init script should be 755

libflashplayer.so has moved in the homedir and is now correct so no
longer needs to have labeling checked.

restorecond supports glob matching and should not complain on multiple
hard links if they match a glob.

So if a file has > 1 link and is an exact match complain, otherwise do not.

Also fix a couple of error messages.
