Hi John, I raised the same question a few weeks ago. See the thread starting at http://lists.debian.org/debian-devel/2010/02/msg00403.html Summary: - Some buildds for slow arches are hosted on DSL lines, making it unpractical to upload very large kernel images (my -dbg .deb takes 424 MB on amd64). => Support could be limited to fast arches with well-connected buildds: i386, amd64, powerpc, s390 and ia64 - Archive space problem => Support could be limited to some flavours (like, only the standard one, for a start) - Buildd disk space: not a problem on the fast arches So, the major blockers seem to be network bandwidth (to upload the packages) and increased build time for the kernel maintainers. See http://lists.debian.org/debian-devel/2010/02/msg00472.html http://lists.debian.org/debian-devel/2010/02/msg00478.html I wonder what we (as Debian) could do about it. Would it make sense to sponsor a very fast machine that the kernel team could use to build the kernels and upload from, replacing kernel-archive.buildserver.net ? > Another alternative would be to turn on the CONFIG_DEBUG_INFO and > CONFIG_KPROBES options, but strip the kernel and modules, but at least > provide some script a user could run to rebuild the kernel with the same > options and compiler to get the debug symbols.

But I > haven't heard anything since then... It isn't that complicated to build your own kernel image with debuginfo, and it takes 30 mins on a fast 8-cores system.
