(Because it will.) I would suggest not going down that route, it only leads to pain and suffering, much more so than maintaining multiple init scripts by hand, via patches over a 1200baud modem line, working from an ancient parisc box running hp-ux.

If we want to support systemd as default init system and other init systems more or less easily, requiring service files and converting them automatically sounds like a good idea. It could even produce open-rc init scripts. And users can choose whatever they like to run.

Re: systemd2init PoC
JFTR I have added support for ExecStop, Exec{Start,Stop}{Pre,Post} and
X-Debian-Daemonize (to pass extra arguments to the daemon when
Type=simple and you want it to daemonize).
The shell script is still far from the universal and complete tool, but
it really makes me wonder – it was really a GSoC project (and not
something GoogleDayOfCode :-P)?

systemd2init PoC
Hey all, I have hacked together a PoC systemd2init shell script on top of augeas-tools (you need at least jessie version) to autogenerate sysv-rc script out of simple service file. It can handle: Environment EnvironmentFile ExecStart ExecReload PidFile Description Right now you need to put the service file to: debian/lib/systemd/system/.service and run systemd2init.sh and it should generate debian/.init.dh It's really a proof of concept, but since we have libconfig-augeas-perl available in the archive, I guess it can be rewritten into dh_systemd_init with little effort (if you don't hate perl) and included in dh-systemd package. The git repository is located at ssh://git.debian.org/git/collab-maint/systemd2init.git, feel free to update, rewrite, etc. O. -- Ondřej Surý Knot DNS (https://www.knot-dns.cz/) – a high-performance DNS server -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
