Out of interest, since I’ve not used the “recommended partion setup” for any install for a while now, is ext4 still the default on most distros?
I recently installed Nobara Linux on an additional drive, because after 20 years, I wanted to give Linux gaming another shot (works a lot better than I had hopes for, btw), and it defaulted to btrfs. I’ll assume so does Fedora, because I cannot imagine Nobara changed that part over the Fedora base for gaming purposes.
