%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.
