An "emerge -uD" will check all dependencies for updates. So that's how |
| 17 |
one is supposed to make a full update. You most certainly don't want |
| 18 |
all packages in your world file. This would include dependency packages |
| 19 |
(e.g. libraries), which might not be dependencies tomorrow (changed |
| 20 |
software, changed USE flags, etc.pp.). And when you do the occasional |
| 21 |
"emerge --depclean", it can't take those "stale dependencies" into |
| 22 |
account, because they are in the world file. So e.g. libraries not |
| 23 |
linked anymore to anything would still be left on the precious disc |
| 24 |
space, because they're in the world file. |
| 25 |
|
| 26 |
I regularly take an editor and trim down my world file (I forget about |
| 27 |
--oneshot very often) to the packages I want to use. Then I run "emerge |
| 28 |
--depclean" to get rid of old cruft (to be sure, I could have done a |
| 29 |
"emerge -pvDn world" before, but I trust myself enough not to shoot |
| 30 |
myself in the foot). |
