Phil,
Thanks for your input. I did find the location of the grub install
modification. Strange thing is, when I restarted the install, grub
defaulted to the MBR of /dev/sdb. I did not change any hardware or bios
settings in between attempts. I have no idea why the change happened.
Once the install was completed, the OS partition showed up as /dev/sda,
even though it showed up as /dev/sdb during the installation process.
Grub is apparently happily residing in the MBR of /dev/sda. Again, I
can't explain it.
If you (or anyone else) has insights to this behaviour, or can point me
to where I can read up on it, I would appreciate it.
Thanks again for all your help.
Monty,
Not much helpful to add, except that I have seen many cases over many
years of using RH/RHEL/FC and derived distros of device ordering
changing among installer/boot/runtime versions of GRUB, among
installer/installed/updated kernels, as well as among different
contemporary distros. PCI slot priority, initrd, modprobe.conf, and
BIOS settings are also variables so interactions among all these
components can be quite complex.
If you really want to dig into it the kernel development and
distro-devel mailing lists would be good starting places. There are
also old threads in CentOS and Fedora list archives, some of which I
participated in, on these issues. If you find any clear and
enlightening docs on these problems, please share.
Cheers,
Phil
