Looks like the other old glibc versions explicitly declare their patches, like this: --8<---------------cut here---------------start------------->8--- (define-public glibc-2.30 (package (inherit glibc) (version "2.30") (source (origin (inherit (package-source glibc)) (uri (string-append "mirror://gnu/glibc/glibc-" version ".tar.xz")) (sha256 (base32 "1bxqpg91d02qnaz837a5kamm0f43pr1il4r9pknygywsar713i72")) (patches (search-patches "glibc-ldd-x86_64.patch" "glibc-CVE-2019-19126.patch" "glibc-hidden-visibility-ldconfig.patch" "glibc-versioned-locpath.patch" "glibc-allow-kernel-2.6.32.patch" "glibc-reinstate-prlimit64-fallback.patch" "glibc-2.29-supported-locales.patch")))))) --8<---------------cut here---------------end--------------->8--- I've updated my patch to do the same thing; see attached. As an aside, when do we remove old versions of glibc? -- Chris
