You can grab the 3.8 kernel from debian experimental http://packages.debian.org/search?keywords=linux-image-3.8 I'm using it on a bunch of machines and I know of a few others using it too. > The plan is as follows: > > 1) Grab the Ceph files from https://github.com/ceph/ceph-client (and put > them over the older kernel sources). If I got it right the files are: > include/keys/ceph-type.h include/linux/ceph/* fs/ceph/* net/ceph/* > drivers/block/rbd.c drivers/block/rbd_types.h > > 2) Make (trivial) adjustments to the source code to account for changed > kernel interfaces. > > 3) Compile as modules and install the new Ceph modules under > /lib/modules. > > 4) Reboot to a standard distribution kernel with up-to-date Ceph client. > I would think you should be able to build a dkms package pretty easily, and it would be a lot faster to build than building an entire kernel, and much easier to maintain. Of course that depends on the degree of integration with the kernel...
