Thanks for exploring new territorry and making sbuild even more useful!

In https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=809443 I suggested
that systemd-nspawn should be considered as a new ADT backend that
would be widely available... and it would be really great if then sbuild
can rely on this too.

I don't think that systemd-nspawn can be used right now to build a chroot
without root rights but it might be something that the systemd developers
might welcome.

Thus I would suggest you to consider whether uchroot can be developed as
a new systemd-nspawn feature. In fact, right now I'm rather annoyed that
systemd-nspawn relies of btrfs for all "ephemeral chroots" and I would
welcome some feature where it can use a tarball as the reference tree.

Cheers,
