Recommending ext4 over btrfs is probably ill-advised nowadays. See the
regular bug reports about running out of /gnu/store directory entries,
for which the documented fix then breaks booting with GRUB.
Instead, just list regular file systems alphabetically. We can bikeshed
bcachefs later ;-)
Move second-class file systems like NTFS to their own section at the end
of the list.
