when trying to move to artix i found that replicating my arch secboot+TPM2+LUKS setup is not documented on the wiki, you can use an mkinitcpio-clevis-hook setup that works, but takes 5 seconds just to open the root drive (bruh). this guide is for those that want to get away from systemd without giving security up, or boot time fanatics that want blazingly fast boot times even with an encrypted root (and I'm both).
I don't think systemd is bad outside of just how bloated it is so this guide will make use of some artix versions of systemd components (e.g. eukify) that are OK by themselves, if you came here looking for something truly systemd-clean i don't really have it (but am ready to help in making it happen)
