It may be easier to fit it in with a diskless configuration. One of
the problems is that in a "normal" (i.e. not diskless) stuff in /dev
is used before you get at chance to mount something over /dev. And
that may or may not be a problem. But the diskless stuff is run so
early in the boot process, it seems like it should be easier to manage
that.
