Good luck!

You're not really on the right list: a *lot* of this has changed for
FC3.

ext3 filesystems can have a label which describes the filesystem. It
sounds as though your hda3 is labelled /. The userspace mount program
can use this to identify a filesystem, rather than the name of the
device it's sitting on.

This is becoming more important: there are more situations these days
when the name of the device will change. Fedora installs will
automatically label filesystems they create.

Note that if you use LABEL in grub.conf, then you will need an initrd
(which will contain a userspace mount, which can identify and boot from
the right filesystem).

At the moment, it might be easier to start from FC2.

Hope this helps,

James.
