It does happen. Oh, so it’s some tutorial out there that leads users to use ‘large_dir’ when they see those warnings? Bah. > I'm not happy with this patch: it's the tiniest possible tweak and > puts a lot of implicit meaning into the default ordering. Yeah. That said, recommending btrfs (it’s now the first and default choice) has implications. It has its pros, but it doesn’t come for free either in terms of usability and observable change in behavior in some cases. For example, we’ll likely see reports of test suites that fail on user machines (btrfs) but work on our build farms (ext4). So I think we should be careful here. Another option would be to document the ‘large_dir’ limitation, or to use a newer GRUB if that limitation has been addressed in the meantime? WDYT? Thanks, Ludo’.
