From caccc40ad01c4159a5a627b17d3db12ac67fa252 Mon Sep 17 00:00:00 2001 From: aszlig Date: Wed, 18 Jul 2018 02:42:27 +0200 Subject: [PATCH] vmTools: Fix BusyBox runtime error in initrd With the recent update of BusyBox to version 1.29.0 in d6aa506e3baa3565eb375bbf8a4e68c3e3134ec9 there is now a new dependency on libresolv. This now throws a runtime error when executing ash, eg. whenever we do something like this: nix-build -E 'with import ./. {}; vmTools.runInLinuxVM hello' The resulting error will be: .../ash: error while loading shared libraries: libresolv.so.2: cannot open shared object file: No such file or directory I tried to override BusyBox with enableStatic, but that still requires parts of glibc: Static linking against glibc, can't use --gc-sections Trying libraries: crypt m resolv Library crypt is not needed, excluding it Library m is needed, can't exclude it (yet) Library resolv is needed, can't exclude it (yet) Library m is needed, can't exclude it (yet) Library resolv is needed, can't exclude it (yet) Final link with: m resolv In the long term maybe switching to a more minimal C library such as musl would make more sense, but for now I just added libresolv.so to the initrd which fixes the runtime error.
