+"""Build multiarch partial local Ubuntu mirror using packetary"""
+
+##############################################################################
+# Design quirks / workarounds:
+# 1. Fuel-agent uses `debootstrap` to build bootstrap and target chroots from
+#    the local mirror; which only uses the "main" component from the first
+#    repository, i.e. does not include "updates"/"security".
+#    In order to fullfill all debootstrap dependencies in "main" repo, we will
+#    do an extra packetary run using a reduced scope:
+#    - only "main" component of the first mirror;
+#    - reduced package dependency list (without MOS/OPNFV plugin deps).
+# 2. If repo structure is not mandatory to be in sync with official mirrors,
+#    we can mitigate the issue by "merging" all repo-components into a single
+#    "main".
+##############################################################################
+# Mirror build steps (for EACH architecture in UBUNTU_ARCH):
+# 1. Collect bootstrap package deps from <fuel_bootstrap_cli.yaml>;
+# 2. Collect all fixture release packages from fuel-web's <openstack.yaml>;
+# 3. Parse new "opnfv_config.yaml" list of packages (from old fuel-mirror);
+# 4. Inherit enviroment variable(s) for mirror URLs, paths etc.
+#    - Allow arch-specific overrides for each env var;
+# 5. Mirror config is defined based on common config + OPNFV overrides;
+#    - Convert old configuration format to packetary style where needed;
+# 6. Package lists are defined based on common config + OPNFV deps;
+#    - Keep track of "main" packages separately, required by debootstrap;
+# 7. Clone/update all mirror components;
+# 8. IF mirror merging is disabled:
+#    - Clone/update "main" mirror component (fix missing debootstrap deps);
+# 9. IF mirror merging is enabled:
+#    - Use `dpkg-scanpackages` to filter out old versions of duplicate pkgs;
+#    - Run `packetary create` on the set of downloaded packages, merging
+#      them on the fly into a single-component mirror;
