Summary:

SELinux prevented mount from mounting on the file or directory
"./Fedora-9-Everything-i386-DVD1.iso" (type "samba_share_t").

Detailed Description:

SELinux prevented mount from mounting a filesystem on the file or
directory
"./Fedora-9-Everything-i386-DVD1.iso" of type "samba_share_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
"samba_share_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."

The following command will allow this access:

setsebool -P allow_mount_anyfile=1
