linux-libc-dev: please include video/uvesafb.h

It seems that there are a number of other directories of userspace header files generated by the kernel install which we do not include. It is probabally appropriate that we include all of these in our package. I will prepare a patch and post it for consideration.

Pushed the patch to both the Jaunty and Intrepid trees. Should be included in the next updates.

SRU Justification:

Impact: Standard header files are missing on a standard install

Fix Description: includes all exported kernel userspace headers in linux-libc-dev

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-intrepid.git;a=commit;h=481456272646803dfb557e82fac6a4ada2b002f8

Risks: low, these files are already installed on Debian

TEST CASE: see bug report

Accepted into intrepid-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Andy this caused a regression with libdrm-dev:
dpkg : erreur de traitement de /var/cache/apt/archives/linux-libc-dev_2.6.27-11.21_amd64.deb (--unpack) :
 tentative de remplacement de « /usr/include/drm/drm_sarea.h », qui appartient aussi au paquet libdrm-dev

I think you shouldn't touch something as fundamental as the linux-libc-dev headers in a released distro; we rely on being able to build packages for security updates and this change might break random packages without us noticing until we need to build them.

I agree - we'd really want a full test rebuild at some point to validate this change. Including it in Jaunty alone should be sufficient, as we won't be doing anything about the v86d Debian->Ubuntu delta in Intrepid anyway.

Yes, this has not worked out in quite the way expected. This was perceived
to be low risk as we were moving into line with the Debian upstream way of
handling these headers. That seems to have been an erroneous assumption.
In that the current Debian upstream state is also broken.

The drm header collision was spotted recently and although we proposed
removing the headers for drm from the change, it was decided that
updating drm to Replaces: the files was a smaller change and would
prevent the need to rebuild the kernel. This doesn not seem to have
worked out right either.

Given the mess that has resulted, it does seem premature to have this
change in Intrepid for sure. Will coordinate getting this sorted out.

Ok we have had to revert this change in Intrepid as there are a number of complex interactions with other packages including libdrm-dev. This is triggering install failures directly and build failures in a couple of key packages. Therefore this is not suitable for a stable series. The change is already in Jaunty and we will work the issues there.

I've accepted the reversion (linux 2.6.27-11.22). Thanks.

This bug was fixed in the package linux - 2.6.27-11.25
