Bug 128094 – Feature request: eselect kernel, option to automatically copy ".config"

• Status: RESOLVED WONTFIX
• Product: Gentoo Hosted Projects

[Description Bernd Pachur 2006-03-30 02:42:38 UTC]

eselect kernel needs an option to automatically copy ".config" from the old src-dir to the new one, when the symlink is changed.

Bad idea to blindly reuse old .configs, IMHO... especially between different kernel patchsets.

I agree, but it could be followed by a message about running make oldconfig.
(i.e., so it is not done blindly anymore).

[Comment 3 Bernd Pachur 2006-03-30 03:09:47 UTC]

sorry for not writing so, but of course there should be a message about using "make oldconfig".
just missed to write it, because it was so obvious for me.

[Comment 4 Jakub Moc (RETIRED) 2006-03-30 04:31:35 UTC]

That was not entirely what I suggested - make oldconfig just tends to produce crap for me if the kernels are too many versions apart or too different. 

[Comment 5 Bernd Pachur 2006-03-30 04:47:07 UTC]

i never had that problem but i tend to upgrade my kernel regularly.

nonetheless there should be an option to autocopy ".config".

it will still be an _option_ and the message can be there.

Interesting idea. Go into a bit more depth of how you think it should work exactly please.

[Comment 7 Danny van Dyk (RETIRED) 2006-06-11 07:25:21 UTC]

Bernd: Ping? Please provided with more details on how you want this
feature to work. I.e, when switching from version A to B, and B has a '.config'
file already, what should be done? This is you feature request after all.

[Comment 8 Bernd Pachur 2006-06-12 02:36:37 UTC]

sorry for not answering earlier. i never got the info-mail.

my ideas are:

1. two additional options:
 --no-config-update
 and
 --config-update

either can be default.

2. if no option is given, some default behavior combined with a question.
 e.g.: do you additionaly want to update your config?
if option is given, do as wished without further questions.

3. copy .config file from old kernel-dir to new dir and either call "make oldconfig" or inform the user that he must call "make oldconfig" manually.

4. probably some check of kernel-versions. if the versions differe to much (e.g.: different major version ;) ) utter a big warning, that the user should carefully check what happens during "make oldconfig" or that "make oldconfig" may fail.

[Comment 9 Weedy 2007-03-04 14:17:27 UTC]

i would like to have the option as well.

Seems not. WONTFIX then.
