[gentoo-dev] Practical suggestion on moving kde/gnome packages

[Dan Armak]

Hi all,

Intro: Hallski and I are searching for a way to implement moving the 
kde/gnome packages to their new locations, I've got a script to update 
/var/db/pkg with the new location. We ned a way to get all users to run it.

First practical suggestion: Take all ebuilds involved, i.e. kde, gnome, and 
everyhting that depends on them. Make them run the script before taking any 
other action, before the DEPEND statements. (The scripts are sourced, right? 
Everything outside the functions will run first.)

Notes:
1. Test on developers first. Run script only if MAINTAINER=yes.
2. Store setting somewhere that the script has already been run, and don't 
run it again. On the other hand, the script does nothing if you run it a 
second time (but it takes half a second of processor time), and it's safer to 
always run it for a time.
3. When will we remove the script from the ebuilds?
4. When we remove the copies of the ebuilds from the old locations?
5. How will this integrate into the job system, in case the system appears 
before we stop using the script? (That's a philosophical question not a 
practical one).

Hallski, hope you're reading this - I'll try to catch you later on cvs too.

Additional explanation: above method is the only one that answers to the 
requirment that the script must run automatically after emerge rsync on every 
user's computer, because we have no way of telling the user to run it 
himself. (That's why we wanted a job system in the first place.)

The other solution would be to make emerge execute the script when run. This 
has the benefits of a centralized approach, but the users need to be told to 
remerge sys-apps/portage, somehow, which is an egg-and-chicken problem.

Hope we can solve this soon,

Another idea: when the operation launches (in any form), there should be an 
announcement with a link to explanations on gentoo-dev and on the gentoo.org 
newspage.
