No. It isn't 100% free. |

Emerge will only remove the stuff it installed. There's absolutely no way |
| 24 |
to guarantee that any file in /etc is not needed any longer. Besides that: |
| 25 |
|
| 26 |
1.- YOU created those files, so you are the one that should keep the track |
| 27 |
of them |
| 28 |
2.- They are not part of the package, emerge will only uninstall what it |
| 29 |
installed, |
| 30 |
nothing else, I would be very angry if a silly package manager starts |
| 31 |
deleting files |
| 32 |
I created by hand. |
| 33 |
3.- you might want to install that package again, and you are probably not |
| 34 |
willing |
| 35 |
to reconfigure it again |
| 36 |
4.- seriously, even three thousand of files in /etc are not a problem. |
| 37 |
They take |
| 38 |
a few bytes or several kb at most. You better look at /usr/src or the |
| 39 |
number of |
| 40 |
installed games and/or icon themes. |
| 41 |
|
| 42 |
In the rest of the three there shouldn't be too much cruft if you stick to |
| 43 |
portage and don't go installing things by hand around (if you do then you |
| 44 |
can't blame portage neither). |
| 45 |
|
| 46 |
Cruft removers base their actions on guesses. I never felt like those |
| 47 |
programs |
| 48 |
really worked at all. If you use one of them you have still to review the |
| 49 |
final list |
| 50 |
before removal (that or you are good at making backups, you know). So I don't |
| 51 |
know what the point is. I would be quicker to clean the tree myself using |
| 52 |
mc and |
| 53 |
some bash magic. |
