And this, folks, is why there will be no “year of the Linux desktop”. The technical difficulties, and the surrounding gatekeeping.
Don’t get me wrong, I’m a dev, I RTFM, but for most people, their computer is just a simple tool, like a hammer or a screwdriver, that lets them do the actual work they have to do. They aren’t any less “real” Linux users. Just users that will go back to other OSes cause it doesn’t work for them and they keep getting told that it’s their fault for not reading the manual.
I don’t have half the world’s RAM to give to ZFS on my budget NAS tho, and Unraid allows mismatched drive sizes, which is pretty attractive to budget users. TrueNAS is definitely great though.
