Bug#844178: Better systemd integration

[Michael Biebl]

Package: exim4
Version: 4.88~RC4-2
Severity: normal

Hi,

having a native systemd service for exim4 would be great. The sysv init
script does a *lot* of stuff though, so I don't know, how easily a
systemd conversion is possible. As an intermediate step, you can at
least help systemd along a little, and tell it, that the sysv init scrip
starts a long running process. For that, the magic # pidfile comment
exists. If that is set, systemd will set the proper type (Type=forking)
and will correctly set the main pid, i.e. it will notice if the main
process this.

So, while I would appreciate if exim4 would provide native systemd
support (and if you any questions trying to that, please contact the
pkg-systemd-maintainers at a.l.d.o m-l), we can a least improve the
status-quo by adding

Thansk for considering,
