RAID-1 boot partition and FC2->FC4 upgrade

[Jack Howarth]

Paul,
    What do you have for your /boot/grub/grub.conf and your
/etc/sysconfig/grub. I have...

default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.6.10-1.771_FC2smp)
        root (hd0,0)
        kernel /vmlinuz-2.6.10-1.771_FC2smp ro root=/dev/md1 rhgb quiet
        initrd /initrd-2.6.10-1.771_FC2smp.img

..etc for /boot/grub/grub.conf and...

boot=/dev/sda
forcelba=0

...for /etc/sysconfig/grub. I am still a tad unclear on the upgrade
the boot loader step. Does it effectively do an initial...

grub
Grub> device (hd0) /dev/sda
Grub> root (hd0,0)
Grub> setup (hd0)

...with essentially an empty grub.conf file? If so then I guess I
should be okay since the installer must repeat those steps later
when the kernel postinst script runs.

ps I have filed this problem under bugzilla...

...in case anyone else has any feedback to add. Oh, I looked
in the postinst script for the FC4 kernels. They call
/sbin/new-kernel-pkg which in turn calls grubby. Since the only
time they use the --bootloader-probe option in /sbin/new-kernel-pkg
is to look for lilo, I guess it should be okay. I do have
backups by am trying not to need to use them.
