Description Karel Zak 2012-04-27 08:44:22 UTC

The syscall mount(2) returns EBUSY on /dev/fd0, because libmount does not close a device file descriptor used originally for filesystem probing.

 # mount /dev/fd0 /mnt
 mount: /dev/fd0 is already mounted or /mnt busy

Fixed by upstream commit 6257e4458295e4a731e3979588e21c95c0cc7186.
