+Subject: [PATCH] deb_driver: Translate repository.architecture
+
+When generating repository metadata, the Release file gets the
+architecture list in an untranslated format, ending up with
+'x86_64' instead of 'amd64'.

+Subject: [PATCH] clone: Create metadata for empty components
+
+In certain scenarios, mirror components (e.g. trusty-security)
+are present in both packetary configuration input, and in target
+system's apt source definitions, but contain no packages of interest.
+
+For such repository/requirements combinations, packetary currently
+skips creating metadata (Release, Packages) for those components,
+which leads to the partial mirror missing some critical files for apt,
+(an empty file would be enough).
+
+e.g.: Using packetary to create a partial Ubuntu mirror, then trying
+to build a bootstrap image from the new mirror leads to:
+
+W: Failed to fetch http://127.0.0.1:8080/mirrors/ubuntu/dists/\
+   trusty-security/multiverse/binary-amd64/Packages  404
