scripts/mkusers: allow users with no password value set
The following allows a user definition to specify that a created user entry should not have a password value set. Original implementation allowed a user definition to provide a password value of "=" (no quotes) to generate a crypt-encoded empty string value. In some cases, it may be desired to have no value specified for a user's password. By using a value "-" for a password, no value will be set in the shadow value. An example when this can be used is when logging into a terminal. Logging into a session with an encoded empty password will prompt a user to enter a password since it does not know the password is empty. If the password field blank, a login session will not prompt for a password. Signed-off-by: James Knight <james.knight@rockwellcollins.com> Acked-by: "Yann E.
