From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.5-ac5 i686) Description of problem: mkinitrd runs losetup which fails over tmpfs. This is probably a bug in the kernel. (I tested with 2.4.5-ac5) How reproducible: Always Steps to Reproduce: 1. mount /tmp as tmpfs 2. run mkinitrd Actual Results: 3. "all your loop devices are in use" Additional info: hacking the mktemp lines from /tmp to /var/tmp solved the problem for memk
mkinitrd looks around for a non-tmpfs directory as of 3.3.1
