In my kernel command line(with busybox), init=/sbin/init, I drop
commands into /etc/profile.

Don't run sh before init, this makes the warning.

runlevels makes no sense here, but it should be OK.


And, I use busybox to build the rootfs for kernel debugging:

the rootfs making script is at here right now:

Might helps.
