Stolen from the Gentoo install documentation, you can mount your
filesystems, chroot into position, and then run your profiles to make
sure your environment variables are set:


   Mount the /proc file system first, copy over the /etc/resolv.conf
file and then chroot into your environment. 

   Code Listing 1.1: Preparing and chrooting
 
   mount -t proc none /mnt/gentoo/proc
   cp /etc/resolv.conf /mnt/gentoo/etc/
   chroot /mnt/gentoo /bin/bash
   env-update && source /etc/profile

I always mount /mnt/boot too...

Then configure and compile your kernel & modules and install, making
sure your grub is ok.

Good luck.   - Jim

Subject: [ale] Is this a brain transplant or a heart transplant?

Hi all,

I'm running Debian testing, and my processor recently died. I used this
as an
opportunity to upgrade my processor and system board, and now I need to
figure
out how to use my old hard drives, which contain a perfectly functional
Debian
system, with my new board and processor. Basically, my question is
whether I
can use my current partititions and data, and just compile a new kernel
to
match my new system board configuration. The system board, processor,
and
several peripherals no longer match exactly, so I definitely need a new
kernel.

I thought I might be able to boot into something like Knoppix, let
Knoppix tell
me what *it's* using for modules, then use that info. to compile my new
kernel,
but I'm not sure how I can do that from Knoppix, and I've not come
across
anything on the web which describes how this would work. Can I recompile
a
kernel just by mounting the root and boot partitions Knoppix recognizes
and
then compile a new kernel using sudo? Would anything I compile in this
scenario
boot properly when I'm done and no longer want to boot Knoppix?

Or, are there some basic parameters I can pass on the command line as my
OLD
kernel (2.6.4) starts to boot that would drop me into a basic root shell
from
which I could recompile? I would have to pass in enough info. to get it
to deal
with my new Pentium 4 processor--the old one was a K7 Athlon.

The worst-case scenario is that I could just wipe out my current disk
configuration and reinstall completely, since I've got my critical data
backed
up, but I'd intriqued by the challenge of getting a new kernel to work
with the
setup I have.

Thanks in advance for any advice.
