Debootstrap help

["Jeremy Wilkins" <jeb@jdwilkins.co.uk>]

Hi,

I'm trying to cross bootstrap debian-arm onto my palmtop from sarge on
my laptop. I've upgraded to debootstrap 0.32 from backports.org. I can
run;

debootstrap --foreign --arch arm sarge /media/cf_card
http://ftp.uk.debian.org/debian/

I then boot an initrd on my palmtop (psion 5mx) and try to

chroot /mnt /debootstrap/debootstrap --second-stage

This fails with
E: Invalid Release file, no entry for main/binary-arm/Packages

Any clues as to what I'm doing wrong?

thanks

jeb
