migrating away from systemd units...

This: http://openrc.run/ doesn't quite get me there...

I have systemd units I wrote for starting VMs, networking (WiFi and Wired) and for starting SSH reverse tunnels.

They use some of the systemd features that I'm guessing don't correlate in OpenRC?

For example:

The VM unit is named "[email protected]" so that I can use the %i variable inside the file and type this "systemctl enable vbox@VM_NAME"

I have a similar unit file for the reverse ssh tunnel. "[email protected]" allows me to type "systemctl enable autotunnel@80" and port 80 gets forwarded back through the tunnel.

This way I have one unit file for every VM I feel like using or port I need to forward, instead of a different, specific unit file for each one.

I have other things I need to clear up, but I just want to solve this one issue of "passing the variable" so I can use a single common file to provide multiple services.

Maybe Open RC wants to do this in a completely different way... I don't know. I didn't invent these things so I have no idea.

Some of this is a bit messy because they wouldn't work according to documentation, and there was no explanation for the failures.

Logic and Reason and RTFM brought no solutions, so I just DuckDuckGo'd for similar stuff and jammed options into the unit file(s) until it worked.

Sloppy and dumb, yes. But, I've got sh*t to do...

Here are the contents of the files:

Since I finally figured out the missing parts of the documentation needed to get Artix running as a headless host AND in a VM, I'd like to get everything switched away from systemd dependent OSes...
