From b44aa8c96e9eea54a42c074c278a8e05e1c231d5 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 15 Feb 2023 10:20:28 +0900 Subject: [PATCH] kbuild: deb-pkg: make .orig tarball a hard link if possible If '..' belongs to the same filesystem, create a hard link instead of a copy. In most cases, you can save disk space. I do not want to use 'mv' because keeping linux.tar.gz is useful to avoid unneeded rebuilding of the tarball.
