[solved] systemd-target for wakeup

Hi guys,

I want a servicefile being executed on every wakeup, bootup as well as recovering from sleep.
The solution I'm thinking of at the moment consists of three servicefiles:
One starting my job, bound to bootup.target or something like this, another one starting the same job bound to sleep.target, a third one that is ment to enable both files when getting enabled itself. This is because I want one servicefile belonging to this one job.

But as this is ugly I would like to have one servicefile. I can bind it easily to sleep.target and bootup.target simply using "WantedBy=" twice, but as the job needs to be executed on *wakeup*, I need to use "After=sleep.target", but I'm afraid that would interfere with activation on bootup, leading to the job being not executed on bootup as bootup is no wakup from sleep and thus sleep.target is not triggered.

Any ideas concerning this? I'd appreciate it.

yes, After/Before have no effect if the listed units are not part of the start process.
