Providing a recovery environment would be *great*. I've seen people post
to the list basically saying "I've hosed my
userland/kernel/everything/forgot my root passsword/whatever. what do I
do?" and the responses usually boil down to "sorry... looks like you're
going to have to do a backup and then use the restore CD to start again".
I use Linux extensively, and really appreciate the ability to root a box
simply by having a recovery CD handy. Adding this ability to the
NetBSD-cobalt toolchest would be a real help.

Agreed. VMWare, for example, will let you run a VM created by not only
it's own brethren, but some other products as well (like MS's VM). IT's
free, too! I tried QEMU in the past some some simple stuff, but I went
crazy because it didn't appear to allow direct access to the floppy and
CD-ROM drives. Kind of a pain when trying to install an old copy of
Windows 3.1 :)

Aah... so the recovery CD provides dhcp, which includes the requisite
information about the NFS/netboot server. I don't remember disabling my
local DHCP server... are there some dirty tricks that the recovery CD
plays, or do I just not remember disabling my DHCP?

That sucks. Was it a driver problem or a usage problem?
Thanks for the good information, and good luck!
