  Is it necessary to put the plaintext password in the .config?  Why not put the
output of mkpasswd in the config, and explain in the help text how to produce
it?  Perhaps even with vVj0miIkzZnhg as an example of password root.  So the
help text could be:

	  Set the root password. This is the crypt'ed password as it should
	  appear in /etc/shadow. To create a password, use the mkpasswd
	  utility: "mkpasswd -m md5" to create an md5-crypted password.

	  Note that sha256 or sha512-crypted passwords are preferred, because
	  md5 is somewhat compromised. However, the default busybox
	  configuration does not have support for sha256 and sha512 passwords.

  Obviously, this will make the patch much simpler, as there won't be a need
anymore to distinguish between no-root-passwd and root-passwd.

  Arnout
