>Does reiserfs still have a large install base that is just very happy with an old stable filesystem? Or have all its users migrated to new and exciting filesystems with active feature development?
It’s a bit of a stretch but I guess you could interpret calling a 20 years old FS “old” as snarky?
Though of course that it hasn’t received any major update in the last 15 years and is fast approaching major issues (iirc it’s not y2038-safe) are factors.
