Hi Everyone,
My program package includes a systemd timer and service. I was able to
setup my Makefile for a regular install using the daemons web page
(https://www.freedesktop.org/software/systemd/man/daemon.html).
My question is, how should I handle a staged install using DESTDIR?
Specifically, should we expect the timer and service to be enabled in
the staged directory? Should we expect the timer to be started in the
directory?
AFAIK, a staged install with $DESTDIR usually means that you're preparing the files to be collected into a package -- usually to be installed on another system and/or at a later time. So it doesn't make practical sense to start anything at this point.
(And honestly I would **never** expect a Makefile to start any services **at all**. Doesn't matter whether it's staged or not: that is simply not what `make install` does.)
It also doesn't make much sense to call `systemctl enable`, as it's mainly a sysadmin tool. Some distros automatically enable & start services after package installation... but in that case the "enabled" status is still under control by the sysadmin -- it is not hardcoded in the package itself.
(Side note: If you *do* want to preset the "enabled" status, you can actually do this without `systemctl enable` by creating the same symlink under /etc or under /usr/lib that the command's output shows.)
So in short I would suggest:
* Staged install: Do *nothing* except for installing the files.
* Non-staged install: Enable the service if you really need to (or create the .wants symlink by hand), but do not start it.
