[RFE] Provide hostname's acceptable format
Originally filed here: https://bugzilla.redhat.com/show_bug.cgi?id=1328236
Windows is a bit picky with respect to the hostname and doesn't accept any of the following characters: {|}~[]^':; <=>?@!"#$%`()+/.,*&
Per Zeeshan's suggestion0, libosinfo could provide this kind of information.
