I think this is a good forward to allow starting to use the tools.

Given this results in alternative dependencies (systemd | systemd-
tmpfiles or however they are named), we should probably be careful with
using this in base/core packages: there is both the limited dependency
resolver by debootstrap and previous experiences with these
alternatives not always behaving as one would like to keep in mind.

Thanks for all your work :-)
