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)?
Instead of any arch-based distro, I recommend using opensuse TW because in my experience with arch it was not great.
If something goes wrong during the system upgrade in TW, you can always rollback to the previous snapshot.
And the update to plasma 6 is just around the corner.
