Subject: - slighty change the message when exiting successfully from install,
 to not mess with abnormal termination - get back dialog for hostname and
 domain in case of unable to guess domain - try to resolve DNS if self-ip
 can't resolve, to guess domain - remember entries so that when there is a
 problem you don't have to re-enter everything (ncurses sucking stuff in case
 of stdio-frontend..) - use larger buffer for list_directory since in /dev
 there can be *many* files
