They were deferred but without going in to the details
I was able to get them posted back. I'll have to leave it
at that.

None that I'm aware of. If you have the code you can run it.

Yes. It's all about PA support for connectivity if your flash
device fails and you need to load a new image remotely.

We are going to try our best to get the image size down if
possible via:

CSCsc63112
Externally found moderate defect: Assigned (A)
7200 boot images exceed 4M bootflash due to image size growth

*without* removing old device driver support but it may be
impossible but at least they are going to try.

It had nothing to do with this for the boot images it was
done for consistency which is the only reason I was able
to get those two posted back for now until and if we can
get it really resolved via: CSCsc63112
