Last change on this file since 1540 was 1540, checked in by Bruno Cornec, 17 years ago

exclude_path should be 4*MAX_STR_LEN everywhere. Fixed now.
Increasing that value will allow to having larger exclude paths.
Should solve bug #137 (and maybe #3 as well)

18110/01 - 10/31
182- changed find_cdrom_device() to ignore DVD drives in the hd[a-d] search;

193- improved find_cdrom_device()

196 assume /dev/cdrom
197- if restoring data then ask for CD-ROM's /dev entry (not its SCSI node)
198- run_program_and_log_output() now takes boolean operator to specify
199 whether it will log its activities in the event of _success_
200- changed sort -n +4 to sort -s +4 (Troff)
201- ask if user's kernel is sane; if 'no' then use FAILSAFE
202- ask user to confirm the tape/CD device name
203- if restoring (not archiving) then don't try to find CD-ROM's SCSI
204 node; try to find its /dev entry instead
205- better detection of biggest partition
206
20708/01 - 08/31
208- fixed verify bug --- CD#1 was being verified again & again & ...
209- detect boot loader + device; if not detectible then _ask_
210- if run interactively, assume tape size is irrelevant & don't ask
211 for it; Mondo should handle end-of-tape gracefully now
212- worked on handling unknowng media size
213- added interactively_obtain_media_parameters_from_user()
214- when trying to mount CD-ROM, find_and_mount_actual_cd() will
215 now call find_cdrom_device() to try to find the /dev entry first
216- fixed serious bug in zero_out_a_device()
217- cleaned up some log_it() calls
218- fixed minor bug in find_cdrom_device()
219- better at distinguishing between live filesystem and ramdisk
220
22107/24/2002
