Description sudhir kumar meena 2010-04-24 06:37:01 UTC

SELinux prevented mount from mounting on the file or directory "mtab".

Detailed Description:

SELinux prevented mount from mounting a filesystem on the file or directory
"mtab" of type "etc_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 "etc_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
