This problem happens during the remove phase ... which includes downgrading
udev+systemd from the version in jessie-backports to jessie.
Maybe it's best to use "jessie + udev/backports + systemd/backports" as the
reference chroot instead of jessie directly.

The situation in jessie2bpo2stretch seems to be better :-)
