Description:
Running an svnserve daemon as a service as a non-root user as described on the wiki does not work. The child process fails immediately without any clear error message in the journal.

Modifying svnserve.service removing the --pidfile argument from the command line solves the issue. Adjusting the permissons on /run/svnserve to allow the non-root user to create the pid file also solves the issue. Running with the official, unchanged unit (as root) works fine.


Additional info:
* package version(s): subversion 1.8.8-1, systemd 212-3
* https://wiki.archlinux.org/index.php/Subversion_Setup#Start_the_server_daemon viewed on 2014-04-25


Steps to reproduce:
- Install the subversion package.
- Create a drop-in for svnserve.service setting User to an existing non-root user.
- Start svnserve.service. There is no error message at this point.
- Viewing the service status shows the error message 'svnserve.service: main process exited, code=exited, status=1/FAILURE'.

How about putting an svnserve.conf under /etc/tmpfiles.d, with the desired user? Like:

D /run/svnserve 0700 the_user the_user -

Yes, that's certainly a solution, but I don't think its the best. Every user wanting to not run as root would have to 1) know the file is needed (= update the wiki) and 2) actually create it, effectively doubling the amount of work needed (writing two config files instead of one).

As far as I can see, the pid file is never read by anything. There is no PIDFile=/run/svnserve/svnserve.pid line in svnserve.service, so systemd doesn't use it, and it still figures out the correct child pid. This is currently the case in my own setup, using a custom unit with --pidfile removed.

I doubt that some other program is reading it (please correct me if I'm wrong here), so if it's not needed and causing trouble, why keep it?
