Description of problem: We use mksquashfs for backups but mksquashfs is now hanging indefinitely. Th eproblem is well described in the following link http://sourceforge.net/mailarchive/forum.php?thread_name=oyd63wy5374.fsf%40cs.rice.edu&forum_name=squashfs-devel
Should be fixed for 3.4 which is now built for rawhide.
