[gentoo-user] Make the user the member of portage group or not?

[German]

Question is in the subject line. Another question I have is there any point to use other frambuffer device ( I currently use efifb) and I am thinking to use fb for my radeon r4 graphics in hopes to get some acceleration. Thanks

And the answer is in your hands? Does not being a member of the portage
group cause any problems for you? If not, you have no need of it.

Quantum leap: (adj.) literally, to move by the smallest amount
theoretically possible. In advertising, to move by the largest leap
imaginable (in the mind of the advertiser). There is no contradiction.

  If the user is a member of portage he can do any emerge operation as
long as the command includes "--pretend" or "-p"

[d531][waltdnes][~] emerge -pv ufraw    

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] media-gfx/ufraw-0.20-r1  USE="-contrast -fits -gimp
-gnome -gtk -openmp -timezone" 0 KiB

Total: 1 package (1 reinstall), Size of downloads: 0 KiB


  However, the regular user is not allowed to actually emerge or unmerge
anything.  E.g...

[d531][waltdnes][~] emerge -v ufraw
emerge: superuser access is required


  The idea is to allow the user to find out what he would have to do if
he wanted to emerge/unmerge something.

Thanks for your answer. It now got clearer to me.

Actually, users in the portage group can "emerge --fetchonly" without 
"--pretent". Also, they can:

   rm -rf /usr/portage

(Or whatever the portage directory is set to.)

This might depend on other settings in FEATURES, not sure. But here, 
/usr/portage and everything in it belongs to user portage and group portage.

You don't need to be a member of the portage group to do that.

[fred@shooty ~ 0]% groups
users
[fred@shooty ~ 0]% emerge -p bash

These are the packages that would be merged, in order:

Calculating dependencies... done!
[binary   R    ] app-shells/bash-4.3_p33-r2 

Being a member of the portage group allows to to write to directories
owned by portage, so you can do things like emerge --sync and
emerge --fetchonly.

You can do fetchonly, but sync is not possible. You need root for that.

You're right, $PORTDIR itself is not group-writeable

Okay, I pulled the pin. Now what? Hey, where are you going?

The main usage for that is if you want to develop ebuilds and test them. So, 
if you want to do for example

ebuild blabla-0.57.ebuild clean configure

somewhere in an overlay or in the portage tree, it helps to be in the portage 
group. (Some more minor steps might be required too.)

If you dont want to do this you should not be in the portage group.
