+Subject: [PATCH] build_image.pp: Extract cluster_arch from "/" URI
+
+Since target image building was moved from nailgun to puppet, we
+need to determine the "target_arch" value differently.
+
+One way to go is to extract it from the root disk image URI, which
+is constructed based on static fixture data in nailgun.
+
+This change relies on the following:
+- image_data contains "/", with a properly arch-qualified URI;
+- image_data "/" URI arch uses the same format as "target_arch"
+  (in this case "arm64" instead of "aarch64" or other variations);
+
+While at it, increase task timeout from 1800s to 3600s.
+
+NOTE: Unlike the previous approach, this method does not rely on any
+other nailgun changes (i.e. adding the "arch" field to the database
+model), but only on `fa_build_image --target_arch=...` support.
