Our agent will support nearly any Linux distro, even though our installation script only supports systemd at the moment.

We've really wanted to add OpenRC support to our installation script for a while but haven't gotten to it yet.

If you know your init system well, you could always write your own service file. Here's the unit file for systemd as a reference: https://github.com/deviceplane/deviceplane/blob/master/insta....

Let me know if you end up getting this to work. Would love to upstream to our install script!

A OpenRC script should be fairly simple, as should a script for the modern van Smoorenburg rc in Debian. They are both largely just scripts of variable=value assignments.

The service file for systemd looks pretty simple, so that's probably not a problem to port to some other init system.

But what's in the "nearly" above, do you have some other concrete requirements for the distro? Any technical reason very small busybox-based systems would be unable to support your agent?

Deviceplane sounds like a very good idea for a niche that really needs something like it!

Delegate=yes is ignored because I did not run this on a Linux operating system.
