+
+This is a small wrapper around `apt-get dist-upgrade`. We use this to
+print additional information (kernel restart required?), and
+optionally run an interactive shell after the update. This binary is
+invoked when starting an upgrade using the web GUI.
+
+If you are already logged in on the console, it is peferable to invoke
+`apt-get` directly.
