> Hi, so it seems we were saying the same thing - new vms get a shared "blank" (empty) file system,  not blank disc.  How big a problem it is that in many cases this will be the already created ext3 disk and not ext4 depends I guess on how important consistency is to you (to me its pretty important).  Either way the change as it stands wont give all new vms an ext4 fs as intended,  so its flawed in that regard.
> Like you I was thinking that we may have to move away from "default" being in the file name to fix this.

Indeed, "default"'s meaning is mutable and thus it is flawed as a
cache key.
