Aaron,
Thanks for the explanation. That makes a world of sense. Since
we are only dealing with VMware at the moment, I forgot that VCL
did handle other provisioning sources.

Currentimage.txt is a simple unique identifier used by vcld to determine
what image is loaded on any node, outside of the hypervisor or
provisioning module. Since vcl can use more than one provisioning
source, this identifier needs to exist.

Of course, now I am a little confused. Why rely on
currentimage.txt, when VCL queries the hypervisor not much
later and can get that same information?

It would see to me that this could be a secondary validation
as this step happens right before the power-off command is
issued.
Nevertheless, I will follow your advice and update our images
to insure the right image name is in currentimage.txt
Thanks.
