enough for a lot of things to have changed. Yaboot operates
somewhat like lilo, so if you want to (later) update it from within
the clfs system you should compile and install it "as normal". The
idea of "stages" is specific to grub. If I understand it correctly,
you can come out of chroot after installing the kernel, Then add
the clfs system to yaboot.conf in the ydl host, perhaps something
like
image=/clfs/boot/clfskernel-2.6.26.whichever read-only
init=/clfs/sbin/pre-init and of course run ybin after this. It is
important to do this on the host system, and to keep the host kernel
details in yaboot.conf, so that you can go back to ydl if the new
system is not found, or doesn't work, or just to use its apps. I'm
not sure if the same yaboot.conf would work if you wanted to run
ybin inside the clfs system. I guess it will (from memory, the
paths to the specified kernels are written to the bootstrap, and
then evaluated at boot-time), but a rescue CD (for the ydl host) is
always a good idea.
-------------------------------
Thanks for the suggestions - In the default ydl-6 configuration, it
appears that there are 3 partitions - the boot partition, the main
partition and the swap partition:
# fdisk -l
Device Boot Start End Blocks Id System
/dev/ps3da1 * 1 13 104391 83 Linux
/dev/ps3da2 14 5664 45391657+ 83 Linux
/dev/ps3da3 5665 5729 522112+ 82 Linux swap / Solaris
I created /clfs on the main partition - /dev/ps3da2. Maybe /boot on
the main partition is somehow linked to /dev/ps3da1 (it's not a
symlink, but maybe a hard link)? I tried to modify yaboot.conf to
boot from /clfs/boot, but it looks like it only looks on /dev/ps3da1
(partition=1). The yaboot.conf on the host ydl-6 system looks like this:
# yaboot.conf generated by anaconda
boot=/dev/ps3da
init-message=Welcome to YDL!\nHit <TAB> for boot options
partition=1
timeout=80
install=/usr/lib/yaboot/yaboot
delay=5
enablecdboot
enableofboot
enablenetboot
nonvram
mntpoint=/boot/yaboot
usemount
default=linux
image=/vmlinux-2.6.23-9.ydl6.1
label=linux
read-only
initrd=/initrd-2.6.23-9.ydl6.1.img
append="video=ps3fb:mode:13 rhgb quiet root=LABEL=/"
image=/clfs/boot/clfskernel-2.6.27.4
label=clfs
read-only
init=/clfs/sbin/pre-init
append="video=ps3fb:mode:13 rhgb quiet root=LABEL=/"
Is there any way to modify yaboot.conf to look on /dev/ps3da2 (whilst
still maintaining the ydl boot capability) or do I somehow have to
link /clfs/boot to /dev/ps3da1 - in case it helps, /etc/fstab is posted below
Thanks
John
