If I edit the world file and I am not sure, I always run -p --depclean. |
| 44 |
That should tell you if you are about to make a boo boo. The package you |
| 45 |
removed will be cleaned out but so will other things. If it starts to |
| 46 |
remove something that you know you want to keep, then you need to figure |
| 47 |
out why that entry was there and what can be put in the world file to |
| 48 |
keep the things you do want. |

The example Nikos used is a good one. If you decide you don't want |
| 51 |
smplayer but want to use mplayer, then you would need to add mplayer to |
| 52 |
the world file so that it will stay but --depclean will remove smplayer |
| 53 |
when you run --depclean. |
| 54 |
|
| 55 |
Nikos is correct on the -1 option tho. That is the same as --oneshot by |
| 56 |
the way. That is the biggest reason that something ends up in the world |
| 57 |
file that shouldn't be there. I would just about bet that we have all |
| 58 |
forgot the -1 option more than once. It doesn't matter how long a |
| 59 |
person has used Gentoo, it just happens. |
