Another thing that I can't get my head round is if it doesn't return, doesn't pre-init time out, quit and carry on anyway, running the stock init?

Ummm. Yeah. I forgot I put that in there. In v5, I plan to put in the facility for there to be a single `B' script that will prevent that from happening.

And I imagine that the stock init mounts pretty much everything except the root filesystem (already mounted) and the /drive0 and /drive1 filesystems (as it remounts them during syncs, so I figure it just retains control over them altogether). Just place a ``mount /proc'' in your script somewhere before it blocks. Of course, you'll need to wait for v5 before it'll be useful, huh?
