Why not zero? If the answer is it can't be used, then, what arbitrary minimum size is too small? (also, given that resize exists, it can be used for storage after a resize.) On 07/23/2015 06:03 AM, Jason Dillaman wrote: According to the git history, support for zero MB images for the

According to the git history, support for zero MB images for the create/resize commands was explicitly added by commit 08f47a4. Dan Mick or Josh Durgin could probably better explain the history behind the change since it was before my time. -- Jason Dillaman Red Hat dilla...@redhat.com
