Hi everyone, 

since Council has approved the creation of a fresh set of EAPI=5 "13.0" 
profiles, I would like to volunteer for creating them. The proposed procedure 
is outlined below in detail, and I'd be happy for comments. 
[If anything below deviates from Council decision, please tell me- not my 
intention.]

One general question comes first, though: Right now, the releases/10.0 profile 
directory does the following things:
* mask too-old portage
* set eapi
* add USE=bzip2

Is there anything unrelated to EAPI=5 that absolutely must be added to the new 
releases/13.0 directory in addition in your opinion? (Whether this is the 
right place and was the right place in the beginning for USE=bzip2 is another 
question.)

###

The procedure (all paths relative to profiles): 

1) create directory eapi-5-files, with eapi (containing 5), skeletons for 
package.stable.mask etc and a readme

2) copy releases/10.0 to releases/13.0, in releases/13.0:
* increase required portage version
* additionally inherit ../../eapi-5-files
* other changes as per question above?

3) for each arch in default/linux, 
* announce on arch alias (to prevent overlapping commits)
* copy default/linux/${arch}/10.0 to default/linux/${arch}/13.0 and 
* change inheritance in the new copy to inherit ../../../../releases/13.0 
instead of ../../../../releases/10.0
* announce on arch alias (so future changes go into 13.0 tree)
[This describes the simple case. I realize that there are differences in the 
directory structure, e.g. powerpc/ppc64/10.0, which is why this step needs 
extra care.]

4) edit profiles.desc and copy all "10.0 lines" to "13.0 lines", with an 
initial setting "dev" (if dev or stable before) or "exp" (if exp before)
This makes repoman check against the new profiles when using developer 
profiles.

5) announce the state on the dev list, urging devs to update their symlink 
manually and !test!

6) wait one / two weeks

7) in profiles.desc, mark all 13.0 profiles stable that were stable in 10.0, 
and remove the lines for the 10.0 profiles. This makes eselect profile now 
only offer the new ones, and repoman test by default against 13.0 profiles.

8) mark all 10.0 profiles as deprecated by creating a "deprecated" file 
(containing the replacement suggestion) in the directory. This makes portage 
warn users to upgrade (suggesting a new profile for them), and repoman ignore 
the 10.0 profiles.

9) long waiting time as decided by Council

###

Everything that does NOT use/inherit 10.0 will remain unaffected, and whoever 
responsible may have to take care of that some time before (in step 10) the 
main profile directory becomes EAPI=5. This means e.g. hardened, ulibc, prefix 
or bsd.

Cheers, 
Andreas
