Eoghan Glynn 6873195cd1 Support zero-size image creation via the v1 API ... Addresses LP 1025353 for the v1 API. Transition image status to active immediately on creation (as opposed to leaving it queued forever) if the size is set to zero from the get-go. The v2 implementation is left unchanged for now, as the image status does not appear to ever transition from queued to active in that case. This change allows an image to be created that simply acts as a properties bucket, but requires no image data. For example, an image created from a booted-from-volume instance where only the kernel, ramdisk ID, and block device mappings are required.
