bug#42242: 27.0.91; emacs.service now requires emacs to be built with -lsystemd

Nicolas Richard
Using emacs-27 branch

I've been using the unit etc/emacs.service, provided with emacs, for
quite some time.

With emacs-27, it seemed to still work (i.e. no obvious error and I can
create a frame with emacsclient) but then systemd decided that the
operation had timed out and killed emacs :

systemd[2465]: emacs.service: Start operation timed out. Terminating.
systemd[2465]: emacs.service: Main process exited, code=exited, status=15/n/a
systemd[2465]: Failed to start Emacs text editor.
systemd[2465]: emacs.service: Unit entered failed state.
systemd[2465]: emacs.service: Failed with result 'exit-code'.

As it turns out, emacs now uses Type=notify (commit
19f5f7b19b0dcdae87476a3fd51c41f840b2b80f) instead of Type=simple, and
this requires emacs to be built with -lsystemd. I didn't have
libsystemd-dev installed, so it didn't work.

Could emacs somehow detect if it's being launched by systemd and warn
the user ?

I would at least expect a word of warning in etc/NEWS, near this item :
** Emacs now notifies systemd when startup finishes or shutdown begins.

I guess what we could do is have Autoconf generate emacs.service,
using Type=notify if and only if Emacs is built against libsystemd.
Not sure whether that's 100% reliable, though.

[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

Can someone please tell me (off the list) what Type=notify and
Type=simple are?

I'm not sure what is the best solution for this. But I would like to
propose the following patch which adds a line about '-lsystemd' in
etc/NEWS. I think this will serve as a warning till we come up with a
solution (if that is required).

Patch is for, 'emacs-27' branch.
