readyToLogin users must upgrade to gcf 2.7

[Sarah Edwards]

All -

Recently InstaGENI fixed a long standing issue which causes SliverStatus calls for medium and large topologies to be prohibitively large [1].  

We believe this change will be largely transparent to most users.  However, if you are a user of the readyToLogin script distributed with omni/gcf, you need to make sure you are running the latest version (gcf 2.7).

To check your version, run the following command:

$ omni --version

omni: GENI Omni Command Line Aggregate Manager Tool Version 2.7

If your version of omni is older than 2.7, please upgrade following these instructions [2] (and check out the release notes [3]).

If you have any concerns about this change, you can contact the Omni and gcf developers at: gcf...@geni.net. 

Thank you!

[1] For those interested in the details, the SliverStatus return previously contained the full manifest in json format resulting in the SliverStatus return for medium and large topologies to be very large.  Sufficiently large returns could make the SliverStatus call time out and not return a useful value.
