That's actually a metapackage - it depends on the dom0 kernel and hypervisor, but doesn't contain any code. There's no need to rebuild it. > Also assuming the fixes are already included in 2.6.29....how should I > build a Debian xen-linux-system-2.6.29-custom-xen-amd64? They are, but there are many other changes in 2.6.29 so it wouldn't be a valid test. > I am familiar with make-kpkg... I'm not sure you can use that for Xen kernels.
