Is there actually any method left to hook into suspend/resume, that
works under systemd and other inits? I wouldn't know of any, which is a
problem for packages like, e.g., hdparm, which has to re-configure the
HDD parameters after resume (see [0]).

I'm a bit puzzled what the current situation of power management in
Debian is, and which packages are actually useful when using systemd. I
removed pm-utils and acpi*, and everything is still working, so I
conclude their functionality is now handled by systemd.

Kind regards
