FC4 --> FC5 need yaboot, OF help

[Mike Hammill]

Dear Paul et al,

Thanks a lot for the tips.  I didn't realize there was a "linux rescue"
and now I'm feeling hopeful.  I made a first pass solution, but it
didn't work.  I think it's maybe not too far off, but I could use some
advice on how to specify my LVM volume properly and how to install the
bootloader.  The details and specific questions follow:

Thanks to the "linux rescue" you mentioned, I pulled together the info.
It's (temporarily) at:
http://www.pdc.kth.se/~mike/Lamby/machine_info  (CPU, memory, PCI)
http://www.pdc.kth.se/~mike/Lamby/lvm_info (my FC4 LVM volumes)
(lamby is the machine's name).  BTW, there is no MacOS on the machine,
so no worries about trashing other volumes.

Yes, all of this worked fine.  The output from ofpath is at:
http://www.pdc.kth.se/~mike/Lamby/bootload_info
It turns out running ofpath -V from within chroot gave the same answer
as running ./ofpath -V on the pnasrat version, namely, 1.0.7.  I was
running an up-to-date FC4, so perhaps that is why.

Also included in the bootload_info file above is:
* my previous /etc/fstab which worked in FC4
* the yaboot.conf FC5 created (not-working)
* my first try at a new yaboot.conf (not working)
* resulting message when trying to install my yaboot.conf

Well, I gave it the college try and put my yaboot.conf in /etc/yaboot.conf, then, following the tips from the Gentoo folks, 
http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml?part=1&chap=10
I tried to install it outside of the chroot environment.  Unfortunately, this didn't work.  I got:
yabootconfig: /dev/VolGroup: No such file or directory
I just had the scary thought that I wiped my old yaboot.conf that worked
under FC4, but I think I kept it.  I'll have to check later.  In any
event, I hope someone's got more of a clue than me.

Best regards,
