This file also seems to require a different syntax to /etc/minidlna.conf. media_dir statements have to be entered on a single line separated by pipes, which systemd then rewrites onto separate lines when it recreates its own version of minidlna.conf

Hi,

I did not originally create the minidlna package (I'm not sure who
did, but it might have been Olaf) for openSUSE so I cannot tell you
why he did it this way. I only maintain currently the package and am
not inclined in changing it a lot. Olaf must have had good reasons for
doing what he did, and he usually knows what he does. That is, if he
made the package.

That said, on openSUSE systems, the config of minidlna is in
/etc/sysconfig/minidlna. You should edit that file. On openSUSE, there
is no /etc/minidlna.conf

your service file failed because it should be using -f
/var/lib/minidlna/minidlna.conf instead of -f /etc/minidlna.conf in
StartExec. The service file of the package does not point to
/etc/minidlna.conf. You probably changed the service file
