You can enter the container and just run a root shell on it with this command:

  # systemd-nspawn -D ~/debian-tree/ /bin/sh

(That's equivalent of single-user mode or a rescue shell on a machine.)

At that step, you can change the root password:

  # passwd root
  <enter new password>

At that point, boot the container again (with "-b") and you should be
able to log in.

I hope that helps!

Cheers,
Filipe
