For most of them, I guess, yes.

Something like that (I wasn't aware of it, otherwise I would probably have stolen it :) but since it had to be done very late in 12.3 release cycle, I modified systemd-sleep to call pm-utils (if available), after running systemd hooks, instead of doing the write to /sys/power/disk. -- Frederic Crozat <fcro...@suse.com> SUSE _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
