I have been trying to slim down LFS for some time now. While my needs
aren't as small as yours I think I can help (point to help).
There are two products in particular, BusyBox and TinyLogin that take
the place of most of the binaries in Linux. These were designed with
embedded systems in mind so they are very small. They are GPL'ed.
As far as the kernel goes, I would love to hear what anyone has to say
about slimming it down.
