Right.
Thats understandable. 2 things:
a.) http://pad.lv/1023179 is a bug that somewhat covers this.  The idea
would be that you could do
 cloud_config_modules-: mounts
 cloud_init_modules:
  - ...
  Althoug Its not htat useful when you're wanting to insert something at
the beginning of that list.

b.) within a stable release, we aren't going to change the default list on
a whim.  We did insert one and SRU it for the apt-disable-pipelining issue
to allow usage of S3 mirrors.  I hadn't considered this negative affect.
   We tried to announce that change as widely as possible.

   But anyway, within a stable release, that list isn't really going to
change.  Thats why they're called "Stable".  So for 5 years, you can use
that user-data on 12.04.  If you move your base to 12.10, you should
re-check the modules.

  I dont' have a better solution than that for you without thinking more.
