That way it takes no effort to keep a clean world file but does take effort to add something to the world file. I have to rebuild a individual package a lot more than I need to install a new package. I learned long ago, don't trust my memory to do things by default. Heck, I have to think about it to remember to add the -N to regular updates still. I been doing that for years. If it wouldn't screw up other things, I'd set it as a default but that causes another set of issues. Go ahead, tell me to do updates in script. ROFL Dale :-) :-)

I haven't used it for a long time, so its behaviour may have changed/improved. The last time I used it I got a *very* long list of "package XXX was added to your world file" kind of message and stopped using it ever since. I may have run it the wrong way - not sure - but thought of warning Grant just in case. With a back up in hand, which I foolishly did not have handy as I was rushing at the time, it is easy to revert any unwelcome changes.

I think it only adds packages that are not a dependency of something else, which may result in a world file that is too lean and over-enthusiastic depcleaning later on.

However, when I used it last time, many years ago, it would somehow figure out what is dependencies. From what I recall, it didn't do a bad job. As you say tho, backup the file before doing anything. At least then there is something to refer back to. Of course, it may be a option to just start from a empty world file and add back what is really needed and just keep running --depclean to see what needs to be added back to the world file. This is like updating a old un-maintained system. In some cases it is best to reinstall but in some it may not take much effort to do the updates just in smaller steps. Thing is, one doesn't know until one starts the process. It all depends on so many variables. Plus, we ain't the ones doing it either. lol Dale :-) :-)

Example, leave Firefox since it is a web browser you use directly, Libreoffice is another example. Other examples may be Smplayer, VLC, digiKam and other similar programs.
