The failure is trying to run
getent group sbuild >> ${chroot}/etc/group
However, this only works as root, and it's only used as a fallback
in the unusual case that the passwd/group databases in the chroot
are out of sync with the base system. The real question here is
why the system databases weren't copied over during the session
setup.
I would suggest trying to run schroot without sbuild and see that
if you start a new session with
schroot -b -n test -c sid-amd64-sbuild -v --debug=notice
and see if there is anything group-related in the output.
After this completes, is there a group file in the schroot
directory? Does
schroot -r -c test -- getent group sbuild
succeed or fail?
Does "getent group sbuild" work correctly on the base system when
systemd is running? How about "getent group"?
sbuild and schroot don't really do anything which should be
affected by the init system in use. Both just make use of
standard POSIX interfaces, and if systemd causes changes in
how these basic libc calls function, that's a bit worrying.
The schroot db copy is as simple as
getent $db >> $chroot/etc/$db
Any more information you could provide regarding the above would
be much appreciated.

Roger
