I'm having trouble fitting everythign in a 1.5MB floppy image (600k
kernels don't help here...), and SSH (even a stripped down one) is
putting me over by about 100k. I can go for 4MB and that *should* give
me sufficient space to do whatever I need (including the tinyX server)
if I stick with uClibc. However, if I can go up to 32MB space (I can
compress this if I have to in order to get it down to size, but that
shouldn't be a problem, they do this on 16MB iPaqs after all :), I can
easily get glibc on there, eliminating the need to carefully go about
choosing apps that are compatibile with the stripped down libc. I
wouldn't even have to use busybox then as space wouldn't be nearly a
concern (did you know busybox statically linked to uclibc can fit a
mostly functional linux system into under 600k?).
I'm also making some "demo disks" that do the NFS root fs and tftp
loading an image into a ramdisk that are coming along nicely.
