Deployment teams can probably just set the "we're resized already" --
so it doesn't actually require extra work...

Chris wants to generate a single image that is chock-full with as many
sample activities as we can fit. It is a veritable squeeze for the
sub-2GB image and will probably trigger the warning.

And I forgot another To Do: add a big note in the release notes
explaining why the output of df is unreliable and variable until the
resize completes. It's bound to surprise a few people ;-)
