That is up to you of course, and being able to ignore is better than
nothing. But creating a new account is not really an option for
everyone. On the system I would like to use this feature the most, I am
not a system administrator, so I cannot create new user accounts. I
maintain a directory for production use of people in my workgroup. I
also maintain my own for testing and development.

Thanks for your work on this patch. At least being able to use
--no-user-cfg will be very helpful.
