But sid of course had a developing version of it. I deliberately switched a mature and heavily-loaded sid to it and after a short struggle got it to boot. But it became very flaky, occasionally didn't boot, didn't shut down, and had other little foibles, so I did a get-selections, installed a new minimal stable (I think jessie was still testing then), upgraded to sid, added systemd then did the set-selections and full rebuild. I don't think all is as well as it might be, but it's OK. I think a machine really needs systemd right from installation to be maximally stable. -- Joe
