Aaron, a few issues I thought of today:
1. Your check looks for /bin/sh in the current environment, not the
install-root environment. This should be fixable by snprintf-ing the
root path to /bin/sh and checking if that exists.
2. Although bash doesn't have an install script, it does have other
deps that DO have an install script. Bash depends on the following
(when all deps are resolved):
kernel-headers, glibc (install file), ncurses (install file),
readline(install file)

The best way to resolve these issues would be to have some sort of
staticly compiled sh...but I don't know if that is practical. Anyone
have some ideas for this situation? It sounds like we can't use the
--root parameter correctly to install a base system without either
installing twice as was stated above.
