Cool. you still need the /ppc/chrp dir in any case ?

I guess yaboot either knows where we where booted from (if the OF provides the
full path in chosen/bootpath), or uses /etc. The yaboot code i remember
defaulted on /etc for CHRP i think.

Ok. I will not enable it for now, as -U sounds very dangerous, and the "Use
with extreme caution" is not so nice also. Please come back to me when you
