202 | - ask user to confirm the tape/CD device name |
---|

209 | - detect boot loader + device; if not detectible then _ask_ |

---|
213 | - added interactively_obtain_media_parameters_from_user() |
---|
214 | - when trying to mount CD-ROM, find_and_mount_actual_cd() will |
---|

---|
217 | - cleaned up some log_it() calls |
---|
218 | - fixed minor bug in find_cdrom_device() |
---|
219 | - better at distinguishing between live filesystem and ramdisk |
