--- Begin Message ---Package: mount Version: 2.11z-1 Umount needs two extra flags: -aa (basically, specify -a option twice) to umount all filesystems *inclusing* proc filesystems which are excluded now -e excludefs . This is needed because proc filesystems and devfs filesystems can be mounted several times, for example in chroot environments. The shutdown sequence needs to unmount those too, but there's no way to say "umount everything except /proc and /devfs". The umountall.sh script of initscripts needs a umount -aa -e /proc -e /devfs .. so that all filesystems are unmounted except those two. This needs to be done by umount itself because scripting your way out of umounting devfs on /dev (needs to be skipped) devfs on /var/chroot1/dev devpts on /var/chroot1/dev/pts (needed by 2.5 kernels) .. is basically impossible because of the interdependancies (devpts and usbfs filesystems mounted on subdirs of devfs and proc) If I have time (yeah right) I'll submit a patch. Mike.

--- Begin Message ---I believe modern inits keep track of container mounts and unmount procfs et al as needed when shutting down. If not, please send such a feature request upstream, see https://github.com/karelzak/util-linux/issues Thanks, Chris
