I believe it takes the default USE flags from |
| 21 |
/usr/portage/profiles/default-linux/x86/make.defaults (since I am on a x86) |
| 22 |
|
| 23 |
The way the system works is that it applies those default USE flags |
| 24 |
unless you say otherwise. The way to alter the default USE flags for |
| 25 |
your system is to edit your /etc/make.conf and make |
| 26 |
additions/subtractions from the USE flags. Basically this is a way to |
| 27 |
customise your system to the way you want it. |
| 28 |
|
| 29 |
This site shows them all and a brief description |
| 30 |
|

http://www.gentoo.org/dyn/use-index.xml |
| 32 |
|
| 33 |
The best way to see what USE flags are currently set is |
| 34 |
# emerge info |
| 35 |
as this takes into account the defaults and all the changes you have |
| 36 |
made through /etc/make.conf |
| 37 |
|
| 38 |
For instance in the default USE flags has |
| 39 |
|
| 40 |
USE="alsa apm arts avi berkdb bitmap-fonts crypt cups eds....(many more)" |
| 41 |
|
| 42 |
If you don't have a printer on your system, there is little point in |
| 43 |
having cups as a USE flag (it will add unnecessary time to compile your |
| 44 |
packages). So in your /etc/make.conf file you can put |
| 45 |
|
| 46 |
USE="-cups" |
| 47 |
|
| 48 |
Same thing if you don't want to use kde, and say you want to have |
| 49 |
mozilla support on your system as well you would end up with. |
| 50 |
|
| 51 |
USE=-cups -kde mozilla" |
| 52 |
|
| 53 |
Then if you run |
| 54 |
# emerge info |
| 55 |
again it will have removed cups and kde from the USE flags and added |
| 56 |
mozilla to the list as well. |
| 57 |

Hope that helps |
