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)?
Excellent, I think you’ll love Arch. EndeavourOS provides a solid base with sane defaults. Having dracut set up out of the box prevents a lot of mistakes. Combining that with systemd-boot should be a reliable base.
