Please, try it again. > > Karel Thanks! This looks good now, see build log at the end. Just for the record. Now we have a little different behavior of -f if you run as root or non-root. $ sudo modprobe -r loop $ ./losetup -f losetup: cannot find an unused loop device: No such file or directory $ sudo ./losetup -f /dev/loop0 ## now loop module is loaded and it works for the user as well $ ./losetup -f /dev/loop0 That's IMO ok, allthough it could be also nice to 1. not have side-effects (modprobe loop) 2. let it work as user when loop is not loaded (just to find out if system has loop support) If that would be possible to implement at all. An argument against 1. and 2. is that the returned device should probably always exist already. Maybe we could add another option "--check-loop-support" which works without modprobe and equally for root and non-root. cu, Rudi ########################## build log of fixed losetup
