Enhancement request: please document how to build kernel in PPA

[Sergio Callegari]

Hi,

It is unclear to me how to build an ubuntu kernel kernel in a PPA and instructions are missing both in the kernel package and in launchpad.

Particularly, I have not been able to find any up to date instruction on how to create a kernel source package with just a trivial patch on top of the current ubuntu kernel and build it in a PPA.

Simply taking the kernel source package, applying the patch, rebuilding the source package and uploading it to the PPA fails to build in the PPA (due to ABI checks, I believe).

- Instructions in https://wiki.ubuntu.com/Kernel/Dev/KernelBuildScripts do not seem recent and appear to involve much more than what is needed for my case. Most important, they fail at the invocation of the build-mkppa command.

- Instructions in http://ubuntuforums.org/showthread.php?t=1682345 seem to work, but they are very unofficial and look like black magic. Specifically, what are those parameters supposed to do and why are they needed? Why do these parameter make the built kernel a very different size than the original one? A minor patch should not make this difference.

Altogether, can up to date, official instructions for building the Ubuntu kernel + a patch in a PPA be added somewhere?

Thanks!

No logs should be required as this is a wishlist regarding kernel/launchpad documentation.

I see the bug marked as invalid. How does one report a problem with the launchpad infrastructure?
