That is exactly the reason I put together the "ramdisk" driver,
which has equivalent functionality as MFS, but has the advantage
of being a "real device" with an attach/open functions that can
be customized to setup/load the memory respectively.
The port-specific rd_root.c module can easily load the memory from
whatever device/media you want. (I did an example implementation
for the i386 port that loads a root ramdisk from the floppy.)
