[systemd-devel] start user-service only with UID greater than 1000

[Jakob Schürz]

Hi There!

I have two services running in systemd --user, which should only be
startet for login-users.
If i put the service-file by a deb-package in /usr/lib/systemd/user, the
service will also be started for Debian-exim, Debian-gdm and other users
with a UID below 1000. And this is not "good"...

Is there a mechanism in systemd --user to start services only for UIDs >
1000 (on Debian... other Distros may have the first login-user with
UID=500... how can i catch this?)
Or is it possible, to start Units only, if the user is in a special
unix-group? For example a group called "cups-fuse" or "backup", then the
service is startet in the users systemd only, if the user is in this group.

For now i have a

[Service]
ExecStartPre=/bin/sh -c '/usr/bin/test %U -ge 1000'

This produces a failed unit... That is not "beautiful" and leads to
wrong thoughts, watching the journal.

I need this services really only for logged in real users. Not
Debian-gdm or Debian-exim. And i need a solution, to activate it per
package-installation automatically for all the users who should be able
to login...

Maybe a Condition for a set usershell or another item, which identifies
a user as a login-user...

Any ideas or suggestions?
