reassign 515695 linux-2.6
retitle 515695 too small maximum loop devices
clone 515695 -1
reassign -1 iso-scan
retitle -1 should warn user if more then 8 isos are available
thanks

As you can see at this snip of kernel source, if not specified you can
only create up to 8 loop devices. So we can only deal with 8 isos.
I've cloned the bug report to iso-scan since it could warn the user in
this case making easier to detect the problem and explaning it to
him/her.
Cheers,
