Require user account setup during kickstart install before %post?

[Pushpendra Chavan]

I tried looking at kickstart documentation and confirmed that the user
parameter in kickstart body is actually an optional parameter which means,
if you don't provide it, kickstart body won't ask you to enter or won't
stop.

In fact, the option to add a user isn't grayed out during kickstart in GUI
if you don't have user param in kickstart. In case someone has access to
the system physically, one can add any user and even make that user a part
of the wheel group, so many actually create a test user with --lock option
so that nobody could utilize adding a user during kickstart.

The best way to deal with this is to create a text file in %pre and utilize
that file using the%include option in the kickstart body.
