Re: [openpsion] Upgrading Brians 5mx woody distro to sarge

The weekend before last I did all the downloading and extraction on my
laptop. Then copied it all to the psion disk to do the installation.

This time I just did the download on my laptop, then copied the sarge
directory to the psion and run the rest of the debootstrap there.

The first method requires a big hack to debootstrap. But I couldn't get
the second stage install to work due to needing to run the install
scripts from the packages. (patch at end of mail)

The second method doesn't require any hacks to debootstrap but I did
make the following changes in order to speed things up. (note that the
extract() change is to make it easy to insert a return if the extract
has been done on another machine.)

Big patch to enable the extract to be done on a different architecture
(I think this is everything but there are some changes to try and get
stage2 working in some other files that I think aren't required here)
