This change would provie kernel rpm packages that provide better dependencies to kernel module packages that use the weak-modules mechanism to allow modules to be used on different (but similar). Specifically, this is intended for use with Centos-based systems (tested with Centos >= 8). rpm on Centos-based distributions will generate extra Provides headers for a kernel if it finds a cmpressed symvers file in it. Not just dependencies of type: kmod(foo.ko) but also dependencies of type: kernel(foo_sym_bol) = 0x112233445566 And therefore if a binary kernel module was built with that specific kernel, the package manager can check if another kernel provides foo_sym_bol and of the same version. This is similar to the tests that The weak-modules script runs at run time. This change installs the file to make the information available to rpm. Using gzip explicitly as with Centos 8 only symvers.gz is tested for. See /usr/lib/rpm/fileattrs/kabi.attr . Centos 9 and 10 also tests for symvers.xz .
