I have. I started out with yard, and took a look at lxa (go to
freshmeat for it), and ended up using yard's rootfs creation methods,
and built my own backend to move the kernel and root onto flash.

:) Been there, done that! I hope this helps:
Make your rootfs, then chroot into it. Write a short little program
that uses getpwent(3), which I'll call pw_test.c:
Something like (not compiled):
#include <pwd.h>
#include <sys/types.h>
#include <stdio.h>
main()
{
struct passwd * entry;
while (entry = getpwent())
printf("%s\n", entry->pw_name);
}
I'll bet it doesn't work correctly on your rootfs, and does in your
normal rh install.
If not, then:
chroot rootfs
strace pw_test
This will dump the syscalls, and you can see which libraries are
missing.
As it happens, I ended up getting the login_utils RPM and rebuilding
login without shadow and pam, to avoid the libraries.
Hope this helps!
