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. > One of these days I will want to write up some of what we did.
