I just installed my second Artix, but had problems with opensysusers not creating system accounts. Everything was fine on my original installation, so I copied the opensysusers package over to the new installation and downgraded from 0.6.1 to 0.5.1. Now I don't get any errors installing mariadb.
help
esysusers package is now used instead of opensysusers
if you do update, it will be replaced by newest esysusers packages
