[gentoo-dev] linux-headers in baselayout

[Ingo Krabbe]

I have a small problem with linux headers as a dependency in
baselayout.  Hmm, I don't know exactly why I encounter it at all:

Linux headers install /usr/include/linux and /usr/include/asm.

A normal developer configuration would be to link
/usr/src/linux/include/linux -> /usr/include/linux and
/usr/src/linux/include/asm -> /usr/include/asm

The configuration headers in linux-headers of course won't match an own
kernel configuration in most cases.

So what am I supposed to do ? Should I fake emerge linux-headers-2.4.19
or are there more sophisticated methods.  Overwriting baselayout ebuild
is no acceptable answer !

Linus Torvalds has said repeatedly that these should match the glibc
headers, NOT your current kernel.  He justified himself, and others have
provided the same and other good reasons not to have those be symlinks.

For some reason, people refuse to listen.

Hmm, yes thats understood, no problem to use it this way.  I'm just a
bit confused about "/usr/include/autoconf.h", which contains different
variables, then the running kernel.  This again is a problem for the
alsa-driver module which complains about missing version information in
modules, that I actually switched off.

I come through that this is a bug of alsa-driver.  Wouldn't it be
usefull to remove autoconf.h at all for secrutity reasons since packages
that rely on the current kernel configuration should be compiled against
/usr/src/linux/include/linux and not against /usr/include/linux ?
