Possibly decades. The ext3 driver, which the ext4 driver is a fork of, could also mount ext2 filesystems.

  It’s been a long time since I’ve used either, but ext3 _is_ ext2, with journaling added on top, right?
  • bombcar 3y ago
    If I recall correctly the journal was stored in a dot file or similar that could only be seen when loaded as ext2.

    Yeah, and ext4 is ext3 with some extra features.
    • chungy 3y ago
      Basically they're all ext2 with different implied feature flags enabled.
