[DSE-Dev] Bug#731212: policycoreutils: restorecon sometimes fails with error 255 unexpectedly (but repeatedly)

[Russell Coker]

Package: policycoreutils
Version: 2.2.4-1
Severity: important

A# /sbin/restorecon -R /dev ; echo $?
0
B# /sbin/restorecon -R /etc/mtab /dev; echo $?
/sbin/restorecon:  Warning no default label for /etc/mtab
0
C# /sbin/restorecon -R /etc/mtab; echo $?
/sbin/restorecon:  Warning no default label for /etc/mtab
0
D# /sbin/restorecon -R /dev /etc/mtab; echo $?
255

I believe that restorecon is not operating correctly here.  Firstly the error
message about /etc/mtab should occur in case D.

The error return should happen in cases B, C, and D if it concerns the warning
about /etc/mtab.

If the error return doesn't concern the displayed warning about /etc/mtab then
it should have an error message telling the user what went wrong.
