The real fix is to make "struct buf" more object oriented, so that
instead of
bwrite(bp)
one does
bp->b_op[BOP_BWRITE](bp)
(possibly through a suitable #define.)
Once this is in place, the UFS layer doesn't have to operate on a
disk and the following things should be within our grasp:
Mounting of filesystems in plain files (rather than using vn)
A real VMFS or TMPFS which uses UFS as naming for anonymous
VM objects.
