Set 'LINUX_MODULE_DIRECTORY' in bashrc. (operating-system-etc-directory): Pass #:kernel to 'etc-directory'. --- gnu/packages/linux.scm | 4 +- .../patches/module-init-tools-moduledir.patch | 168 +++++++++++++++++++++ 2 files changed, 171 insertions(+), 1 deletion(-) create mode 100644 gnu/packages/patches/module-init-tools-moduledir.patch (limited to 'gnu/packages') diff --git a/gnu/packages/linux.scm b/gnu/packages/linux.scm index 46f2178488..518b0e41b9 100644 --- a/gnu/packages/linux.scm +++ b/gnu/packages/linux.scm @@ -133,7 +133,9 @@ version ".tar.bz2")) (sha256 (base32 - "0jxnz9ahfic79rp93l5wxcbgh4pkv85mwnjlbv1gz3jawv5cvwp1")))) + "0jxnz9ahfic79rp93l5wxcbgh4pkv85mwnjlbv1gz3jawv5cvwp1")) + (patches + (list (search-patch "module-init-tools-moduledir.patch"))))) (build-system gnu-build-system) (arguments ;;
