My thoughts exactly. Once the VFS layer is sorted out, it
shouldn't be a problem to load the file system modules as
KLDs later on. Also, we could write something a pseudo-VFS
module which can be used to stack a module for a root file
system; this way, the actual root is a pseudo VFS and there
is an on-disk file system which sit on top of it.
This will make it easier for writing root support in file
systems, and you wouldn't need to modify file systems so
much for it.
