wrenwrite failed: i/o error means that kfs (the on-disk
file system) is trying to write a disk block and getting
an error for whatever reason.  kfs isn't actually started
until after you type the user name, so it could well
be that it's not making any progress whatsoever.

if you've used plan 9 before (on another machine), you
might try:
	1. boot the install floppy
	2. instead of typing at the menus, draw a new window.
	3. run "disk/fdisk -p /dev/sdC0/data >/dev/sdC0/ctl"
		this sets up /dev/sdC0/dos, /dev/sdC0/plan9, etc.
	4. run "disk/prep -p /dev/sdC0/plan9 >/dev/sdC0/ctl"
		this sets up the partitions inside the plan9
		partition: /dev/sdC0/fs, /dev/sdC0/9fat, etc.
	5. run "disk/kfs -f /dev/sdC0/fs"
		this starts kfs
	6. run "mount /srv/kfs /n/kfs"
	7. poke around in /n/kfs

my bet is that you won't get to step 7, but knowing exactly
what happens will help.  it's easier to debug kfs problems if
you have a full window system at your disposal as well as the
ability to type commands.
