diskparts reads existing paritition information from the disk, it does not write anything.

amd it's just a short rc(1) script, that typically runs "disk/fdisk -p data>ctl",
 and "disk/prep -p plan9>ctl".  with this setup prep is subpartitioning the
plan 9 partition.

it's worth a read.

textonly is not available in the 9atom usb install, but that doesn't mean it's
obsolete.

both prep and fdisk take the "p" command which will print the current partition info.
prep(8) is a good reference.  btw, "fossil" and "9fat" are not partition types.  prep doesn't
use that concept.  they are partition names, and by convention they have the obvious use.
