It is a common misconception that ext3 or ext4 are different filesystems: they are both extensions over the ext2 format and they were always intended to work like that. You can currently create plain ext2 filesystems on FreeBSD and add ext3/4 features on top and it will work just fine. The distinction on linux about ext2/3/4 is rather accidental: they didn't master Version Control in time to branch instead of forking the implementation a couple of times. It also seems like ext3 disappeared. > Seems minor but I think worth it for discovery/pola/obviousness, and a > good time (early in the 13.0 cycle). > > We get a lot of user questions about ext*fs support on FreeBSD and > pointing to an ext2fs man page also feels a bit weird. > This has to be "fixed" through documentation.

We should probably even try to document the format, as I recall we do for FAT somewhere(?). Pedro.
