I don't like btrfs, this seems to be the default fs for the boot
partition with openSUSE Tumbleweed and I think on 2 occasions it got
messed up so bad that I stop using it.
Anything is better than btrfs, even fat32 which I ended up using for the
boot partition! Been running solid with no issues upgrade after rolling
upgrades.
This is a solid fs, there are times when I see the reactions from users and I really wonder why I do open source work anyway. I have lost data on all sorts of filesystems, and I have also been at the end of stupid mistakes made. Almost everything is recoverable if you stop, and ask for help and keep your ego out of it.
