Fedora 16 preupgrade with grub2 failure.

Mon Feb 27 05:07:50 UTC 2012

Thanks for your info - I finally punched through - here's what mine
needed to look like:

title Fedora F16
	root (hd0,0)
	kernel /vmlinuz-3.2.7-1.fc16.x86_64 ro root=/dev/mapper/vg_hostname-lv_root
	initrd /initramfs-3.2.7-1.fc16.x86_64.img

where hostname is my host name.  This is in fact the grub2 version
(ported back to grub).  Previously I had misread the first '_' as '-'.
 (no copy/paste in the little bash world I was struggling in)

I notice that /dev/mapper/vg_hostname-lv_root is a symlink to ../dm-2
- I hope it's ok to mount /dev/dm-2 directly - I might not have a typo
in a name that short, and I might even remember it! :-)

Since I don't need anything fancy, can I simply keep grub and not
fight through getting grub2 to install?  I'm worried that my 200 MB
/boot/ partition is not up to the task.  It causes me trouble every
single upgrade.  (I know I need to do a fresh install with a new
partition map - I promise eventually to get around to that.)

Thanks for any advice,
Julius
