I've tried to correspond this to the systemd source and unit files and I think I might have found something of relevance. One of the last links in the chain is that poweroff.service gets started and calls "systemctl --force poweroff", right? In my log, poweroff.service gets "installed" to be run: [ 57.887771] systemd[1]: Installed new job poweroff.service/start as 243 but never gets run. By that I mean: When other services are queued to be started, they later get started with "About to execute" messages e.g. [ 57.941081] systemd[1]: Installed new job alsa-store.service/start as 250 [ 60.373390] systemd[1]: About to execute: /sbin/alsactl store [ 60.450713] systemd[1]: Forked /sbin/alsactl as 1505 [ 60.456367] systemd[1]: alsa-store.service changed dead -> start However, the poweroff.service never gets any of the 'about to execute', 'forked' or 'dead->start' messages. It actually gets stopped for some reason, perhaps before it has had a chance to do its thing? [ 57.887771] systemd[1]: Installed new job poweroff.service/start as 243 snip [ 87.312551] systemd[1]: Installed new job poweroff.service/stop as 347 [ 87.340953] systemd[1]: Job poweroff.service/stop finished, result=done However, I think it should have been ready to run. from poweroff.service, its requirements/dependencies are: Requires=shutdown.target umount.target final.target After=shutdown.target umount.target final.target and all of those seem to have finished: [ 87.255264] systemd[1]: Job shutdown.target/start finished, result=done [ 87.284275] systemd[1]: Job final.target/start finished, result=done [ 87.353693] systemd[1]: Job umount.target/stop finished, result=done Am I onto something here, or am I going in the wrong direction? Debugging tips much appreciated. cheers Daniel _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
