libsystemd has been renamed to systemd-libs, you might want to rectify that.

Fixed, thanks for the heads-up

seems pacman no longer uses '--force' so the script fails to run lines 54,55 unless '--force' is removed.

Replaced with '--overwrite'.

I'd like to fork this - is there a license?

Free for all.

Ah, the new init is alphabetically before openrc now and needs explicit installation. Should be fixed. now.

Hey there! Apparently the script is unable to find artix-archlinux-support

Artix no longer depends on any Arch repos to operate, artix-archlinux-support is redundant and not needed for the conversion. Updated.
