Bug description:
Binary package hint: binfmt-support
As part of LTSP fat client installations, the following instructions are
performed (cut down version):
$ chroot "$ROOT" mount -t proc proc /proc
$ chroot "$ROOT" update-binfmts --import wine
$ umount "$ROOT/proc"
At this point we get:
$ umount: /opt/ltsp/i386/proc: device is busy.
$ (In some cases useful info about processes that use
$ the device is found by lsof(8) or fuser(1))
...and we're forced to resort to `umount -l` to work around this problem.
Is the any way to call update-binfmts in a chroot (e.g. to install wine)
without having to resort to `umount -l`?
