Bug#608428: schroot: [kfreebsd-*] cannot handle long (>= 14 chars) chroot names
Package: schroot
Version: 1.4.16-1
Severity: important
On kfreebsd-*, schroot is not able to unmount everything if chroot name
is longer than 13 characters:
# schroot -c 123456789abcde echo Hello world
Hello world
E: 10mount: umount: unmount of /var/lib/schroot/mount/123456789abcde-e7de3ef4-e02c-430c-b9d9-0e4eb34f3bd0/dev/f failed: Invalid argument
E: 10mount: umount: unmount of /var/lib/schroot/mount/123456789abcde-e7de3ef4-e02c-430c-b9d9-0e4eb34f3bd0/dev failed: Device or resource busy
E: 10mount: umount: unmount of /var/lib/schroot/mount/123456789abcde-e7de3ef4-e02c-430c-b9d9-0e4eb34f3bd0 failed: Device or resource busy
E: 10mount: rmdir: failed to remove `/var/lib/schroot/mount/123456789abcde-e7de3ef4-e02c-430c-b9d9-0e4eb34f3bd0': Device or resource busy
E: 123456789abcde-e7de3ef4-e02c-430c-b9d9-0e4eb34f3bd0: Chroot setup failed: stage=setup-stop
If the name is longer than 18 characters, it cannot even run a command:
# schroot -c 123456789abcdefghij echo Hello world
E: 10mount: mount: dev : File name too long
E: 10mount: umount: unmount of /var/lib/schroot/mount/123456789abcdefghij-cf720545-3204-4bda-93a8-82bbd3ac46ca/ failed: Invalid argument

Given that e.g. sbuild-createchroot creates chroot named
"$SUITE-kfreebsd-$CPU-sbuild" (which is >= 23 characters), this is quite
an unfortunate limitation.
Also, please don't try my examples at home, because the only way to
unmount stuff mounted by schroot seems to be: put SESSIONS_RECOVER="end"
into /etc/default/schroot and reboot. :/
