David, All,
Hi Yann,
On 2013-11-11 10:11 -0800, David Cohen spake thusly:
Is there a plan to fix 'make oldnoconfig' option?
I currently have need to it :)
I've tracked a thread fixing 'make olddefconfig' where 'oldnoconfig'
option is reported as a known bug, right?
Sorry, I don't understand what your problem is.
Maybe I assumed it was more 'known' then it actually is :)
Care to explain in details what problem you have:
- what you start with
- what you do
- what you get
- what you expected
The bug with 'oldnoconfig' is: 'make oldnoconfig' is just an alias to
'olddefconfig'. Any non-existent config is defined with its default
value instead of 'N'.
I work with embedded platforms. I need to maintain a set of defconfigs
for different products (customers some times want tailored configs, so
creating a generic one isn't an option always).
make allnoconfig KCONFIG_ALLCONFIG=oldconfigfile
I'll give it a try. Thanks!
I use this trick in http://landley.net/aboriginal/FAQ.html#dev_miniconfig
And yes, I submitted it upstream a couple times last decade, with
documentation and everything:
You could send it again.
I linked you to three times I sent it:

Plus I made sure it worked in busybox and uClibc:
http://lists.uclibc.org/pipermail/uclibc/2007-March/038469.html
Other people picked up on it:

http://techoverflow.net/blog/2013/07/09/user-mode-linux-for-beginners-part-1-setup-and-first-vm/
Somebody even added it to the Documentation directory a few years back
(while I wasn't looking):
https://www.kernel.org/doc/Documentation/kbuild/kconfig.txt
The problem was the kbuild maintainer at the time categorically rejected
the idea in a very long thread. (The replies to that "take 2" lasted two
weeks.) He was the maintainer, his no was final, so I went off and did
other things.
But maybe oldnoconfig would be a better name WRT current standard.
Br, David
As you can see from the rapid response time, I'm a touch overwhelmed of
late.
I've been offering miniconfig stuff to people for years, but the
upstream guys had zero interest when I pinged 'em and still don't, last
I checked. When Linus yanked the giant forest of arm defconfigs he
decided to have kconfig snippets generate different defconfigs instead
of miniconfig (which turns out not to be particularly maintainable, but
oh well).
If somebody else wanted to take the basic concept and push it upstream,
I'd happily review and ack, but I haven't got it in me to replicate the
7 years the initramfs guy spent convincing upstream to Do It My Way. I
scratch my own itch, offer it to other people, they say no, and after
about the third attempt I go do other things. My todo list runneth over,
no shortage of other things...
