I've been doing quite a bit of development on a platform based on FreeBSD
4.11 recently.  I can agree that it will be a very substantial upgrade
indeed!  FreeBSD 4 is pretty old and crusty (in particular, the age of its
network stack really shows).

This is only the case because the default FreeBSD kernel configuration
installed by the system installer has an option that causes it to be
so.  You can build a NetBSD kernel like that too; just hardwire the disks
to the channels and master/slave positions in your kernel config file,
instead of using * and ? to wildcard them.

However, with RAIDframe this is not necessary, because it will find the
disks by their component labels.
