I tested it a bit in a VM to get familiar with pacman and yay. Latest KDE Plasma 6 and more snaps in Ubuntu’s future are the main reasons I want to switch.
As I don’t use a separate home partition, I have an extra drive with BackInTime home dir backups and virtnbdbackup snapshots.
Is EndeavourOS stable enough for everyday use and would restoring home with BackInTime just work (as root user)?
The only thing I want to add is that installing arch the right way doesn’t matter if you have installed any linux distro manually. You could install debian the arch way if you wanted to and still come out with the same skill set.
