-
-The mirror stores all the data in a docker volume at path
-`/var/mirror/ubuntu`.  Map that somewhere else if you like.

-* `UBUNTU_MIRROR_ARCHITECTURES`
-    * default `amd64`.
+* `MIRROR_ARCHITECTURES`
+    * default `amd64`. 
     * You may want `i386,amd64`.
-* `UBUNTU_MIRROR_CATEGORIES`
-    * Default `main,universe,restricted,multiverse`. Will use lots of disk.
-    * You may want `main,universe`.

     * You may want `xx.archive.ubuntu.com` (where `xx` is your country
       code).
-* `UBUNTU_ENABLE_SOURCE_MIRRORING` - do we want to mirror all the source code too?
-    * Default ``
-    * You may want `1` if you want to use up even more disk for your mirror
-* `MIRROR_UPDATE_INTERVAL_SECONDS` - mirror update interval
