Then we have to keep two copies of the files options LIFFS has changed,
and make sure that changes in one go into the other.
That's a mess.

But it was not implimented as a seperate filesystem. It was implimented as
ffs with larger inodes. The first 128 bytes of a large inode are treated
the same as the first 128 bytes of a small inode.
If you really don't like it, you don't have to define options LIFFS. :-)
