Hi Mark,

Thank you very much for your detailed comments.

sysvinit and  busybox, tinilogin require eglibc libc-crypt support.

And busybox need libnsl, so I try to finger out how to break these 
depencies.

I will test it.

RP suggested using mdev provided by busybox instead, I'll do it later.

First of all, I do the minimal with your direction and give you feedback.
