Bug#772555: init-system-helpers: deb-systemd-helper does not respect systemd Preset files

[Raphael Hertzog]

Hello Andreas and debhelper maintainers,

I saw the move of update-rc.d to init-system-helpers in 805487 and the bug
mentioned some plans for further changes to move dh_systemd_enable and
related functionality to debhelper... I would like to draw the attention
of people interested in that to the wishlist below: we should be able to
use systemd preset files but we can't because initial installation doesn't
call "systemctl preset" in deb-systemd-helper...

I would very much like to see this fixed in stretch and while it's
relatively straightforward, when I try to think about the details, I
always get lost on how it should be done... I have troubles with the
init-system-helpers codebase and its interactions with the various
init systems. Andreas, given your recent involvment in
init-system-helpers, is it something that you'd be willing to tackle?

If it can help, Kali is willing to sponsor the work to get this feature
done... get in touch with me if you are interested.

Cheers,
