This isn't unique to the FreeBSD implementation; it's just part of the design. Most Linux systems now use ext3fs, which is basically ext2 with journaling added. I kind of share Aditya's perspective that what you're trying to do is a bit odd, although it might be a good way to squash bugs. Still, what's next...trying to run make world on an msdos filesystem? ;)
