Summary: Directory to install third-party binary kernel modules for kernels %{kernelversion}.%{patchlevel}.x
Group: System/Kernel and hardware
%description -n kernel-%{kernelversion}.%{patchlevel}-rosa-flow-abi
This package contains a directory to install third-party binary kernel modules for kernels %{kernelversion}.%{patchlevel}.x.
Some vendors provide binary-only kernel modules. They can put them into /lib/modules/%{kernelversion}.%{patchlevel}-rosa-flow-abi.
kmod tools will find them for kernels 5.4.x of "generic" and "nickel" flavours,
but there is no guarantee that these modules will load and work correctly on newer
or older kernels then the ones they were build against.
We call this "flow ABI" because most ABIs are not changed between %{kernelversion}.%{patchlevel}.x releases,
but there are no specific guarantees. ABI may evolve and change.
We highly recommend to use DKMS and build third-party kernel modules from source for every kernel!
This package does nothing, just owns a directory for third-party binary kernel modules.
