Hard disk upgrade

[Timothy Murphy]

I've found that upgrading Fedora-14 to Fedora-15 has been very simple,
with no problems at all, even though I am keeping the same /home partition,
which has caused problems (mainly with KDE) in previous upgrades.

However, I had one problem trying to do a hard disk upgrade
on a machine with no internet access, but running Fedora-14.
I copied Fedora-15-i386-DVD.iso to / (/dev/sda5) via a USB stick,
and copied isolinux/vmlinuz and isolinux/initrd.img to /
(after "mount -o loop").

Then I re-booted with the grub stanza
-------------------------
title Fedora 15 install
	root (hd0,4)
	kernel /vmlinuz repo=hd:/dev/sda5:/Fedora-15-i386-DVD.iso
	initrd /initrd.img
-------------------------

This booted OK, up to the point where I chose my uk keyboard,
but then said it could not find the (somewhat garbled) repo.

Is there something wrong with the above line?

If I omitted the repo=... then the machine booted fine,
but then looked for an internet connection, which it did not have.
[I actually solved the problem in the end by running a 20 metre
ethernet cable up the stairs to the attic where the computer was.]

There were two other probably unrelated side-issues:
1. I noticed that Knoppix-6.4.4 called the hard disk /dev/sde .
2. When I re-installed grub with Knoppix
it booted Fedora-14 (and Windows XP) fine,
but said that /vmlinuz was now an incompatible format.
However, when I re-installed grub again with Fedora-14,
/vmlinuz was accepted.
