I built those images natively on the Zaurus, not by cross-compiling, so the
process is very straightforward (though slow).  It is basically a
debootstrap, with some extra (nonessential) packages installed, then with
some bits removed like documentation.

Then use "mkfs.jffs2 --pad=14811135 --eraseblock=0x20000 --little-endian" to
create the image.  In order to get it to fit, I had to add hardlink support
to mkfs.jffs2 (patch in the BTS under mtd-tools).

Here is the process I used for stripping down the system:

        rm -rf /tmp/initrd
        mkdir /tmp/initrd
        cp -a ...nfs export.../* /tmp/initrd

        # Remove cruft from using the tree for a live system
        rm -rf /tmp/initrd/var/cache/apt/*.bin \
                /tmp/initrd/var/cache/apt/archives/*.deb \
                /tmp/initrd/var/lib/apt/lists/debian*

        find /tmp/initrd \( -name '*~' -o -name '*.dpkg-*' -o -name '.nfs*' \) -print0 \
                | xargs -0 rm -f

        # And remove some useful stuff that we can live without
        rm -rf /tmp/initrd/usr/doc /tmp/initrd/usr/share/doc \
                /tmp/initrd/usr/man /tmp/initrd/usr/share/man \
                /tmp/initrd/usr/share/locale \
                /tmp/initrd/var/lib/dpkg/info/*.md5sums \
                /tmp/initrd/var/lib/dpkg/*-old \
                /tmp/initrd/etc/X11/xkb \
                /tmp/initrd/usr/X11R6/lib/X11/locale/[^C]* \
                /tmp/initrd/usr/X11R6/include/X11 \
                /tmp/initrd/sbin/fsck.ext3 \
                /tmp/initrd/usr/bin/localedef \
                /tmp/initrd/usr/bin/apt-cdrom \
                /tmp/initrd/lib/libslang* \
                /tmp/initrd/usr/share/info \
                /tmp/initrd/usr/X11R6/lib/libXft.so* \
                /tmp/initrd/usr/lib/libfreetype.so* \
                /tmp/initrd/usr/lib/gconv

        rm -rf /tmp/initrd/tmp
        mkdir /tmp/initrd/tmp
        chmod 1777 /tmp/initrd/tmp
