What about amending the patch to use cp --reflink=auto ... ? The kernel-install tool is what would need to be patched. It is what is doing the copying at install time. Doing it in the spec is pointless as we're mucking around in the build root not the actual system. josh ___ kernel mailing list kernel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/kernel
