Date: Tue, 11 Jul 2023 17:31:17 +0200 Message-ID: <20230711153126.28876-3-msuchanek@suse.de> X-Mailer: git-send-email 2.41.0 In-Reply-To: <20230711153126.28876-1-msuchanek@suse.de> References: <20230711153126.28876-1-msuchanek@suse.de> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-kbuild@vger.kernel.org There is an ongoing effort to limit use of files outside of /usr (or $prefix on general). Currently all modprobe.d paths are hardcoded to outside of $prefix. Teach kmod to load modprobe.d from $prefix/lib. On some distributions /usr/lib and /lib are the same directory because of a compatibility symlink, and it is possible to craft configuration files with sideeffects that would behave differently when loaded twice. However, the override semantic ensures that one 'overrides' the other, and only one configuration file of the same name is loaded from any of the seach directories.
