It's a perfectly reasonable solution to implement ext4 in base with a BSD implementation, but no one has taken this on yet. Even if importing GPLv3 in base wasn't an issue, you can't simply copy the code. Extensive kernel/VFS and userland changes would need to accompany it. It's not a trivial task otherwise it likely would have already been done. Besides, ext4 is just a poor excuse for SU so what's really the point? If you really want to use ext4 then use it natively. Same problems exist in the Linux world for it's non-native FS's. -- Adam
