+Subject: [PATCH] Don't use file timestamp in cache filename
+
+Every file in the nix store has a timestamp of "1", meaning that the
+filename would remain constant even when changing zoneminder versions.
+This would mean that newer versions would use the existing symlink to an
+older version of the source file.  We replace SRC_HASH in nix with a
+hash of the source used to build zoneminder to ensure this filename is
+unique.
