An old Arch to Artix conversion script that might be of use to someone
#!/bin/bash
# LICENSE: MIT
#TODO:
# - need to check and make sure this script is up to date with the migration process [ ]
# - the script doesn't seem to work when I have been testing it. it does most of the stuff
# properly, however it doesn't seem to get the install *quite* right. I need to do
# much, much more testing before I can properly use this
#run this script as root
#also checkout the new migration article on artix's website, they added in init specific documentation
