    installer: Allow special characters in passwords
    
    Store the password in an environment variable and pass it to the pw(8)
    command.  This way of passing passwords allows special characters in the
    password.  Actually, adduser(8) uses the same method to deal with the
    password.  So this closes the old bug #3027.
    
    In addition, this prevents the plaintext password from appearing on the
    command line or in the installation log file.  Although the installer
    will print every executed command to the install.log (located at
    '/var/log/install.log' with mode 0600 though), the root password setting
    and new user creation steps belong to the 'configuration' stage rather
    than the 'installation', so currently the plaintext passwords won't go
    to the install.log.

    in bug #3027.
