commit 132b59b2b5587eee0c8f66abea4bed28532f30e4

    Avoid setting empty root password (#964299)
    
    When using kickstart with no rootpw command, imgcreate ended up calling
    "passwd -d root", leaving the root account password-less.  That may lead to
    local or remote privilege escalation.
    
    This change does the following:
    
    1) There's no password manipulation done when password is empty string and
       rootpw was not called with --iscrypted
    2) Password is locked when "rootpw --lock" is used
    
    Notes:
    Users can still shoot themselves in a foot by using: rootpw --iscrypted ""
    
    Resolves: rhbz#964299 (CVE-2013-2069)
