Attached is 'crawl-user-data' that just mirrors the http to local filesytem. It relies on the list output shown above.

I'll attach the output when run in a EC2 instance also.

The importance of 'low' is fine as long as it doesn't mean "this will
never get fixed".

I've considered changing ec2-init to crawl the metadata service early on
and then make the data available in files in /var. This would be both
faster and more secure. Right now any process has access to the entire
metadata service, which possibly contains sensitive information.

Scott-

Could you re-run these commands against Lucid, as Dan would like to see what's there, and what your current expectations are?

---------------
eucalyptus (1.6.2~bzr1189-0ubuntu1) lucid; urgency=low

  [ Thierry Carrez ]
  * debian/rules: Start publication jobs on package install (LP: #504326)
  * debian/*publication.upstart: Do not advertise Walrus, SC, CC or NC if
    eucalyptus authorized_keys is missing, since autoregistration would then
    partially fail (LP: #513722)

  [ Dustin Kirkland ]
  * Merge from upstream bzr revision, should fix:
    - LP: #453416 - fix metadata subdirectory lists
    - LP: #513842 - fix metadata ephemeral verbage
