Dear all,

I have gotten a new avc., after applying the updates, the other ones disappeared :)  Hope that was just it.  




SELinux prevented umount from mounting on the file or directory
"/media/.hal-mtab-lock" (type "mnt_t").

Detailed Description:

SELinux prevented umount from mounting a filesystem on the file or directory
"/media/.hal-mtab-lock" of type "mnt_t". By default SELinux limits the mounting
of filesystems to only some files or directories (those with types that have the
mountpoint attribute). The type "mnt_t" does not have this attribute. You can
either relabel the file or directory or set the boolean "allow_mount_anyfile" to
true to allow mounting on any file or directory.

Allowing Access:

Changing the "allow_mount_anyfile" boolean to true will allow this access:
"setsebool -P allow_mount_anyfile=1."

Fix Command:

setsebool -P allow_mount_anyfile=1
