### when the immutable flag is set, the ro option is required
### for the mount command to succeed

+=====+
suse-xen0:/xen # ls -l /xen/*.iso
-rw-r--r-- 1 root root 3749740544 Sep 29 09:45 /xen/OpenSuse.10.1.i386.iso
suse-xen0:/xen # lsattr /xen/*.iso
------------- /xen/OpenSuse.10.1.i386.iso
suse-xen0:/xen # chattr +i /xen/*.iso
suse-xen0:/xen # lsattr /xen/*.iso
----i-------- /xen/OpenSuse.10.1.i386.iso
suse-xen0:/xen # mount -o loop /xen/OpenSuse.10.1.i386.iso /mnt
/xen/OpenSuse.10.1.i386.iso: Permission denied
suse-xen0:/xen # mount -o loop,ro /xen/OpenSuse.10.1.i386.iso /mnt
suse-xen0:/xen # echo $?
0

### when the immutable flag is unset, the ro option is not required
### for the mount command to succeed

suse-xen0:/xen # chattr -i /xen/*.iso
suse-xen0:/xen # lsattr /xen/*.iso
------------- /xen/OpenSuse.10.1.i386.iso
suse-xen0:/xen # mount -o loop /xen/OpenSuse.10.1.i386.iso /mnt
suse-xen0:/xen # echo $?
