In addition to the dependency issue, dhclient needs the interface as
parameter; this has been fixed upstream already, and I left an
additional comment in the Debian bug with the patch needed to backport:
https://bugs.debian.org/775514#68

You can workaround locally with the following instructions as root:
1) # cd /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/
2) # tar xzf init.tar.gz
3) patch the 'init' file with the changes in
https://github.com/libguestfs/libguestfs/commit/2d2a65504dca732a398d237565b9778f8ca828b5
4) # tar czf init.tar.gz init
5) # rm init

Now the network should be working.

Thanks,
