That all sounds good.

right after typing root, so we must end up somewhere here
(busybox/loginutils/login.c):
if (pw->pw_passwd[0] == '!' || pw->pw_passwd[0] == '*')
goto auth_failed;
if (opt & LOGIN_OPT_f)
break; /* -f USER: success without asking passwd */
if (pw->pw_uid == 0 && !check_securetty(short_tty))
goto auth_failed;
/* Don't check the password if password entry is empty (!) */
if (!pw->pw_passwd[0])
break;
..
auth_failed:
..
puts("Login incorrect");
As you're using the default fs skeleton, the pw_passwd[0] and
/etc/securetty tests shouldn't fail, but apparently they do. Could you
enable strace and run
strace -f login
And send the output to the list?
