[Solved] Informing user services that a system target has been reached

thePhysicist8 · 2016-10-22 20:47:06

I have a bash script running as a systemd user service that I want to use to mount an sshfs share automatically whenever the network comes online. I was originally intending to use network-online.target to accomplish this, but that is a system target which can only be used to trigger system services (services running as root).

I was wondering if there is a way that I could create a system service that activates with network-online.target and sends any instances of the user service a signal telling them to mount.

The users running this service will not have root privileges, so on-demand mounting via the fstab isn't an option. Something like afuse isn't an option either, as I don't want to bring in any extra dependencies, especially ones that aren't in the repos.

A quick and dirty way would be to have the system service create a file (e.g. /tmp/networkonline) and the user instance has a .path unit for that file which activates the user mount service.

You can also write a user service that connects to the system manager over dbus.

I tested ukhippo's suggestion and I think it will work for me. Thank you both for the responses.
