I've not tested it without systemd, however the only reason systemd is used is to trigger the execution via an inotify watch on snapshot creation. If you look at the two files here (https://github.com/jmylchreest/refind-btrfs-snapshots/tree/main/systemd) you can see the cmd it executes and the inotify condition that triggers it.
As long as it runs with permissions, typically root, you could run it via icron or an inotifywait script, or just on a schedule via cron/whatever triggers snapper/snapshots being created. There's a few arguments, but the ones in the systemd unit should be reliable.
Please log an issue on GitHub if you have issues, I'd be happy to help get it working there and if you do use an alternative please leave a note/update the readme in a PR.
I am using artix linux and want to try this. Would it work without systemd? If yes, can you make a documentation about it?
