Maybe /boot on > the main partition is somehow linked to /dev/ps3da1

^^^^^^^^^^^^^^^^^^^^^^^^ I've no idea what that line means, or does,
but it makes me wonder if ps3da1 is indeed mounted at /boot or at
/boot/yaboot. Oh, your fstab shows an ext3fs at /boot so I guess it
is indeed mounted there. Unusual on ppc, but not outlandish. >

0 0 What is the layout of /boot ? Maybe you'll need to copy the
clfs kernel to it (space permitting, of course). In fact, the
/path/to/clfskernel needs to be how yaboot will find it at
runtime. That means it probably has to to be on the same
partition. On a mac, we can run 'ofpath /dev/sdX' to get the open
firmware path to an image on a different partition (section 12.4).
On a mac, yaboot.conf is copied to the apple_bootstrap partition by
ybin, and is read during the boot (bottom of Appendix E in the ppc64
book). You quite clearly don't have this sort of partitioning.
Google found that booting on ps3 apparently used to need kboot, not
yaboot. Unclear if that was just for the initial boot. I wonder if
ydl's version of yaboot has been patched for the ps3 (check the
source rpms). ? 'man yaboot.conf' on your ydl system is probably the
best I can suggest. Perhaps it specifically mentions the ps3
? Maybe try 'ofpath /dev/ps3da2'
Thanks - after some more investigation, I found the following output
from the mount command
/dev/ps3da2 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/ps3da1 on /boot type ext3 (rw)
spufs on /spu type spufs (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
So it does indeed look like the /dev/ps3da1 partition is mounted as
/boot on the /dev/ps3da2 partition.
I could see that I could do this prior to compiling/installing the
kernel, which would install the clfs kernel alongside the ydl kernel
in /boot - but I'm kind of lost as to how to set things up on reboot
so that the clfs kernel loads (effectively from /dev/ps3da1) and
/clfs/sbin/pre-init gets called from /dev/ps3da2 ??
