Call 'deduplicate' only when SIZE is greater than %DEDUPLICATION-MINIMUM-SIZE; otherwise call 'dump-port'. * nix/libstore/gc.cc (LocalStore::removeUnusedLinks): Drop files where st.st_size < deduplicationMinSize. * nix/libstore/local-store.hh (deduplicationMinSize): New declaration. * nix/libstore/optimise-store.cc (deduplicationMinSize): New variable.

There are more changes that can be made in the future, but these changes seem like a good start. * config-daemon.ac (guix_substitute_urls): Add https://bordeaux.guix.gnu.org. * guix/scripts/substitute.scm (%default-substitute-urls): Add http://bordeaux.guix.gnu.org. * guix/store.scm (%default-substitute-urls): Add bordeaux.guix.gnu.org. * doc/guix.texi: Adjust accordingly. * doc/contributing.texi: Adjust accordingly. 2020-12-11maint: Remove unused 'NIX_VERSION' macro.Ludovic Courtès * config-daemon.ac: Do not define NIX_VERSION. 2020-12-11maint: Avoid macros obsolete in Autoconf 2.70.Ludovic Courtès * configure.ac: Require Autoconf 2.69. Use 'AS_HELP_STRING' instead of 'AC_HELP_STRING'. * m4/guix.m4: Likewise. * config-daemon.ac: Use 'AC_CONFIG_HEADERS' instead of the singular variant.
