Summary:      package kernel and initrd for OBS VM builds
Version:      1
Release:      0

%description
This package is repackaging already compiled kernels to make them usable
inside of Open Build Service (OBS) VM builds. An initrd with some basic
kernel modules is generated as well, but further kernel modules can be 
loaded during build when installing the kernel package.

%prep

%build
# a longer list to have them also available for qemu cross builds where x86_64 kernel runs in eg. arm env.
# this list of modules where available on build workers of build.opensuse.org, so we stay compatible.
