mksh is an excelent /bin/sh replacement. Much lighter than bash

If you want to use mksh like that you'll have to use my rc_nobash
initscripts and you'll have to do the following as root:

    ln -sf mksh /bin/sh

ldd won't work because of a bashism. I got a fixed glibc in my
repo. Or just check the patches in that dir if you don't want to
rebuild glibc
