Subject: kernels on the restore CD

While trying to create a restore CD for 3.0, I have started poking
around in the install scripts, and found an oddity.
The script I am looking at is /nfsroot/install/scripts/install-core.sh.
There is a function therein install_boot() that looks like this:
printmsg "Setting up boot partition..."
$MOUNT $ALTROOT_DEV /mnt
# Copy boot loader and the kernels as a backup measure
$CP /cobalt/binary/kernel/boot.gz /mnt/boot
$CP /cobalt/binary/kernel/netbsd.gz /mnt/boot
$CP /cobalt/binary/kernel/netbsd-GENERIC.gz /mnt/boot
for i in $RAQ_KERNELS; do
$LN boot.gz $i
It mounts /dev/wd0e, copies from the restore CD boot.gz (this is the one
from Dennis' original restore CD), netbsd.gz (from the version of NetBSD
being installed, in my case 3.0) and netbsd-GENERIC.gz (also from 3.0).
Then it iterates thru the $RAQ_KERNELS list (vmlinux.gz
vmlinux-nfsroot.gz vmlinux_RAQ.gz vmlinux_raq-2800.gz) and links each
one to boot.gz.
In the instructions.txt file, it notes that if the installation fails,
you should manually boot, manually mount /dev/wd0e, and link each of the
alternative names to netbsd.gz.
Which is correct?
After restoring from Dennis' restore CD, it seems that all kernels are
linked to boot.gz, and the Qube boots. After restoring from my 3.0
restore CD, all the files are still linked to boot.gz (as per the
install-core.sh script, above) but it does not boot.
If I manually link all the alternative names to netbsd.gz, the Qube does
boot (albeit tries to mount root from tlp0, but that is another problem).
To aid my understanding of the files in the /boot directory, is the
boot.gz - created by Dennis(?) to boot a kernel called netbsd.gz
vmlinux.gz - booted automatically by the Qube's firmware
netbsd.gz - the NetBSD kernel
If that is correct, then vmlinux.gz should be linked to boot.gz, and
when the firmware loads vmlinux.gz (i.e. when it loads boot.gz), boot.gz
should take over and start netbsd.gz.
