I am a bit familar with LVM. Can I use this on one partition only instead of
the whole disk? So far I always used chroot in standard directories, but
debootstrap failed in the end with this:

W: Failure trying to run: chroot /data/chroot/buildd/sid mount -t proc proc /proc
W: See /data/chroot/buildd/sid/debootstrap/debootstrap.log for details

chroot: failed to run command 'mount': No such file or directory

I dimly remember that I have to mount the proc directory on the host system,
but this error message is not very helpful.

It is the standard kernel from debian-ports, but I think Thorsten has the
same version on is webpage. I tried to build my own with the crosscompiler
packages from Thorsten, but the build failed...

How do I use a memfile to use this area, or where do I get a fixed
bootloader?
