No major problems (other than I forgot network manager runit). Two things the removing systemd cruft fails (error at do). Also SigLevel should be restored once system it up and running. Is grub update really required?
Mkinitcpio (initramfs) is run several times during switch... running it again to update bootloader seems pointless.
Anyway Artix runit is up and running on my laptop so more than happy ;-)
