Not to mention the times when it seems some large number of files get a change in CVS ID or whatever for some reason (and no other change (for example someone put a tem change in some subset of the rc.d files and then removed it) which seems to happen regularly, then you have to go i i i i i i i i i i i i i i i for 10 minutes, and then you get into finger-typeahead and it then goes right past the one file you DIDN'T want to change and you have lost /etc/master.passwd or something. I really like Mergemaster but it needs options like the one you just removed to make it livable. The -U option goes part way towards this.. How does it know what files have not been user modified? Does it store hashes from the last run somewhere?home | help
