+%description
+Meta-package that provides the kerneldevpkgs-current data file and
+helper script used by kmodtool to discover which kernel version to
+build kernel modules against on Azure Linux.
+
+The kernel version is explicitly set to the Azure Linux kernel version
+rather than queried from the build chroot, which would resolve to the
+upstream Fedora kernel.

+# the helper script appends arch at runtime based on build host)
