I didn't mean to lower our standards; I wasn't sure if that policy of
ours was strict, since a few system services do not have corresponding
tests, IIRC.  I wary a bit that demanding a system test for each added
service may cause scalability problems in the long run, as each demand a
disk-heavy image to be generated and the test to run in a VM, which
makes it expensive/slow.  On the other hand, it's nice to know about any
regressions when they happen rather than on a reboot...

If we have such a policy, perhaps we should explicit it in
our documented contribution guidelines?
