SELinux is preventing /usr/sbin/afsd from 'read' accesses on the lnk_file mtab.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that afsd should be allowed read access on the mtab lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep afsd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-06-03 20:28:14 UTC
restorecon -v /etc/mtab

Does this fix the label?

Otherwise try 

restorecon -R -v /etc

Fixed in Rawhide.
