I a long-time user of RH stuff. I have to chime in here in support of
Mikes gripe with the LABEL= garbage. That is a level of system
abstraction that does not do anything productive. By the time there is a
PROBLEM and I need to work fast at moving a partition to another drive,
I sure dont want to have to go find out which partition is /boot mounted
on. Sure it's LABEL=boot but that doesn't feed nicely to dd, now does
it? The label is a nice thing but is should be just that, a label, an
extra tag that is used only as a reminder of use. Otherwise, /boot which
on one system is really /dev/sda3 and another system /dev/hda2 can be
found fast with "cat /etc/fstab".

On the kernel issue, most of the $$ distro$ have backported patches to
their "official" kernel. That can be a PIA to work from. So far, Fedora
has only used (that I have caught) a stock kernel.org kernel with no
extra patches. So the /boot/kernel*.config file can be used to build
another kernel with the same setup from a stock kernel source. I like to
use the distro kernel to initially boot with and then "roll my own"
using the supplied config file as a starting place to take out the parts
I don't need until the kernel is as lean as I can make it. I really
don't _need_ every module there is no matter how cool the tech is :)
