I didn't quite do this, but nearly, just to make it easier for me <smile>:
1) install ltsp normally
2) tar up the opt/ltsp/1385 directory as new.tar.file
3) boot the ebox2300 (or any target) with knoppix. I used 5.1.1 in text mode
4) fdisk, mkfs.ext2, on the flash
5) mount /dev/hda1 /mnt # mount the flash
6) cd /mnt and untar the new.tar.file
7) mkdir /mnt/boot and /mnt/boot/grub
8) put the bog standard ltsp-vmlinuz and initramfs.gz in /mnt/boot
7) make a /mnt/grub/menu.lst to boot the kernel with 0 delay
8) grub-install --root-directory /mnt /dev/hda
I downloaded ltsp-kernel-kit.
In initramfs I made a dev/hda1 and modded init to mount the flash:
--------------------------------------------------------------------------------
#!/bin/sh
echo
"==============================================================================="
echo "Running /linuxrc"
echo "Mounting /proc"
mount -t proc /proc /proc
echo [debug] exec /bin/sh
mount /dev/hda1 /newroot
umount /proc
echo "Doing the switchroot"
exec /sbin/switchroot /newroot
echo "Hmm, switchroot must have failed!!!!"
exit
---------------------------------------------------------------------------------
and made the initramfs (build_initramfs)
I also played with the etc/rc.earlysysinit and rc.sysinit to NOT load modules,
built a kernel with all drivers needed and no modules, left out lib/modules
lib/share/zoneinfo and also left out the mod-tools from the 'build' to fit
everything on a 256M flash.
It's quick (quicker than the pxe versions even) and works perfectly.
Finally what I really did: a batch file that unpacks the .tgz's
from /opt/ltsp/packages and automated the changes by having an 'extra'
directory that is copied ontop of the i386 (ltsp root) after removing
etc/localtime link.
extra has everything I want eg ssh keys, grub stuff etc in the file system
order eg

This is all slightly fudged. I cannot see how the ltsp system works now (4.2)
as opposed to older. No tmp ramdisk is created. so I did it as it used to be
done:
eg from rc.earlysysinit
-----------------------------------------------------------------------------------
...
#==============================================================================
# Start with the basic inittab file
#
echo "Creating ramdisk on /tmp"
RAMDISK_SIZE=${RAMDISK_SIZE:-"1024"}
/sbin/mke2fs -q -m0 /dev/rd/0 ${RAMDISK_SIZE}
/bin/mount -n /dev/rd/0 /tmp
cat /etc/inittab.base >/tmp/inittab
-----------------------------------------------------------------------------------
and my build script
-----------------------------------------------------------------------------------
#! /bin/sh
echo "===================== rm -fr i386"
rm -fr i386
echo "====== installing files into i386"
tar xzf /opt/ltsp/pkg_cache/ltsp-glibc-1.0-1-i386.tgz
...
...
tar xzf opt/ltsp/pkg_cache/ltsp-util-linux-1.1-0-i386.tgz
cd i386
chmod 755 *
chmod 555 proc
chmod 1777 tmp
echo "================ rm etc/localtime"
rm etc/localtime
echo "== rm -fr usr/share/zoneinfo"
rm -fr usr/share/zoneinfo
echo "======= find . |cpio -pdv ../i386"
cd ../extra
find . |cpio -pd ../i386
---------------------------------------------------------------------------------
Hope that this shows you what you need :-)
