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)?
Setup Btrfs + Btrfs Assistant, rollback if any update breaks things you need.
It’s stable enough for me everyday use but this will depend on your use case + hardware setup. Even some people will swear by Manjaro for years without breaking. I found that usually if stuffs break in Arch, i can fix it but not so much if stuffs break by update from Ubuntu/Fedora.
How good is your performance (especially gaming) with btrfs compared to ext4?
I haven’t noticed any major differences between btrfs and ext4. Having said that, I mostly only play one game on Steam - Red Dead Redemption 2
