Frankly, I don't know. It seems there are about three different places for system-wide service files on Debian and I don't know if the /etc/systemd/user/ is for user-supplied services or for user-services installed system-wide or whatever. I read that /etc/systemd/system is the place for things to go in and which will be untouched by apt upgrade. > > > contents: > > > > [Unit] > > Description=jackd > > After=sound.target > > [Service] > > User=peter > > Does systemd allow Group=audio Had success without Group setting (see other email) now, thank you! > > > ExecStart=/usr/bin/jackd -d alsa -r 44100 -P > > Would it be better starting a bash -l -c to wrap jackd? I would like to execute it from systemd right away to benfit from its restart features, inter-unit dependecies and logging facilities. > You seem to be wanting to run this before any user is logged in.

I am trying systemd for the reason given above. There "must" be an advantage of having it inside my OS and I want to put it to use. :) > OK, from: > http://man7.org/linux/man-pages/man5/systemd.exec.5.html > Group=audio > would start things as group audio and may have trouble writing logs etc. to > the user directorys. > starting the commandline with + has some effect on this but if that opens > things or restricts them I am not sure. > SupplementaryGroups=audio may give both group=user and group=audio > Systemd should be set up for security and as such default to a lower > security level rather than higher.
