The command losetup /dev/loop1 -f /tmp/tfile_loop1 does not make sense. The option -f is mutually exclusive to <device>. You cannot force losetup to use loop1 and in the same time ask to use the first free device (-f). The right way is: losetup /dev/loop1 /tmp/tfile_loop1 or losetup -f /tmp/tfile Yes, losetup should be more smart when it checks command line options. The current behaviour when it tries to blindly use <device> as well as -f is stupid. This issue is improved by upstream commit c3f5a0f1d47dbc47f6d21da232d4eb1cfb7905db. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
