unfortunately usb disk devices are not directly partitionable.
this can be solved on 9atom with sdloop

	addloop u /dev/sdU1.0/data

this will create /dev/sdu0/^(ctl data) which you can then partition
with diskparts.  (if using the standard distribution use diskparts(8) and
the file will be /dev/sdXX/data)

if you do a pull as glenda, or alternately

	mount /srv/boot /n/root &&
		9fs atom &&=20
		disk/mkfs -vkU -s /n/atom/plan9^`{pwd} -d . <{echo +}

you can then try "mkusbboot -p `{echo +}".  this may actually work.
let me know if it has not, as i haven't had a chance to test it.

mpler that writting rc script)?

cd /sys/src; mk install && mk clean

there is not enough room on the usb key to install all.
