If this is not going to the right place, please let me know. If it
is, I'd like to know that too. Thanks.
The addresses I have are:
raymondc@microsoft.com for linux/scripts/Configure
?? for linux/Makefile
?? for linux/README
linux-kernel@vger.rutgers.edu for linux kernel stuff. (To which I'm
not subscribed.)
This patch is to support "batch", i.e. non-interactive, kernel
configuration. That is, you can use a .config file you've saved
somewhere and use it to re-configure a new kernel without having to
hold down the \n key in "make config". If there's a new kernel
configuration parameter, the script has to stop and ask you about it.
I've forgotten details about "make config" and had hassles too many
times, so I wrote this.
The patch contains tabs and so likely will mess up your Makefile if
you cut and paste it from this message. Best to get it from
ftp://ftp.meme.com/pub/software/patches/batchconfig.patch.gz.
The patch should be applied by:
cd /usr/src/linux
patch -p1 < batchconfig.patch
Notes:
I'm working off a 2.0.30 kernel. I've no idea what's going on in the
latest releases. Hopefully not too much new config stuff and this
patch will apply. (I don't really want to spend the time it takes to
download the latest kernel, sorry.)
I dunno who maintains the Makefile or the README.
I dunno the convention regarding introduction of variables into the
Makefile. In particular, the kernel configuration symbols all seem to
start with "CONFIG_" and so I deliberately avoided starting the two
variables I added with this string. I did check to see that the
strings didn't show up anywhere else in the kernel.
Likewise, I introduced one of those weirdo internal targets
"_batchconfig" into the makefile. I'm not a makefile wiz and don't
know whether this is good style or what.
I used some tabs for formatting in scripts/Configure. Dunno if this
is kosher.
The patch works for me, but nobody else has tested it.
The regular copyright used in the linux kernel is the copyright used
for this patch. (So that it can drop right into the distribution
stream.)
I'd appreciate a note from the maintainers so I know if this gets
used. Thanks.

NOTES on "make config":
- having unnecessary drivers will make the kernel bigger, and can
