Description John Watzke 2011-02-10 05:07:47 UTC
SELinux is preventing /bin/mount from 'read' accesses on the lnk_file mtab.

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

If you believe that mount 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 mount /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
