OK, using disk space I understand. Even taking up time and making emerge world longer I understand. How an unused library causes a possible security risk is beyond me but I'll accept it's a possibility for the sake of making forward progress. > > > > > If you want to pick individual packages from "emerge -upv world" for > > > merging, merge them with the --oneshot argument to prevent them being > > > added to world. > > > Humm....OK, or go back once in awhile and clean up your world file by > > hand. > > Assuming you can remember which files you do and don't want, out of the > hundreds of extra lines you end up with in world.

I'm just faced with what's happening this morning. emerge world had 6 things it wanted to update. One of them (MythTV) is running right now. Running emerge world would result in MythTV files being changed while the program is operating. I don't think that seems like a safe thing to do so I don't want that one. I emerge the other 5 by hand. Granted, I think about your point as I do so. I'm not overly bothered by the disk space issue, or even to a great extent the time to compile issue. The basis of your argument is that I'm installing and uninstalling apps which doesn't happen much here. Stuff goes on, it doesn't much come off. If I use only emerge world then I have to wait until the machine is idle and unneeded for long periods of time. I cannot know that with any certainty when the machine is 400 miles away... > > But you really shouldn't recommend this sort of bad practice to others > without at least warning them first. Mea culpa. If I'd known that someone considered it bad practice I most likely wouldn't have. In this case I do (personally) still think it's about choice. I've never run emerge --depclean. The warnings are too severe. The man page is too scary. I won't touch it so I would imagine there are others like me too. For those of us that won't run depclean I think there is not real downside to doing this, but maybe I'm missing some finer point. > > The world file is a powerful concept in portage, if used correctly,. > Filling it up with a list of all installed packages completely negates > its usefulness. Completely negates? No, not hardly. Reduces? Most possibly, but I do not see a way to update my machines otherwise. I get that this is probably just me. cheers, Mark -- gentoo-user@gentoo.org mailing list
