[systemd-devel] Q: Roles for a one-shot service

[Ulrich Windl]

Hi!

I wonder: I'm thinking of a monitoring-type of one-shot service that should be run periodically to update some external status display with runtime data.
In addition to that periodic activations, I'd like to run the service also during boot and shutdown, possibly supplying a special parameter to indicate that a boot or shutdown is happening.
I'm unsure how to model that with systemd. Should I define one service or three services?
Any proposals?
