The idea is that an sdk will comprise of a manifest(contains list of
sstate items in the sdk) and some location that contains the items in the
manifest. So to update the sdk you would run a command and give it the
location of the manifest and sstate, and it would make your sdk match what
is in the manifest.

So the sstate could be hosted on a webserver, nfs, locally, etc.
