Comment 6 for bug 1939974

In a focal chroot on a lunar system:

$ sudo apt install ubuntu-dev-tools
$ mk-sbuild --arch s390x jammy
$ schroot -c jammy-s390x
E: 10mount: mount: /run/schroot/mount/jammy-s390x-b4220f6e-610c-49e6-ab0c-60eb067368c2: unknown filesystem type 'aufs'.
E: jammy-s390x-b4220f6e-610c-49e6-ab0c-60eb067368c2: Chroot setup failed: stage=setup-start
$

Um ok then.

$ sudo sed -i -e'/aufs/d' /etc/schroot/chroot.d/sbuild-jammy-s390x
$ schroot -c jammy-s390x
(jammy-s390x)vorlon@homer:/tmp$ ls
(jammy-s390x)vorlon@homer:/tmp$
logout
(focal)vorlon@homer:/tmp$

So I don't appear to be able to reproduce the original bug?
