Description
Perhaps the default should be that mapping an rbd image creates a new /dev/rbd* if one does not exist for the image, and then creates a symlink, perhaps in /dev/rbd/ ? mapping the new alias to the same device. That would prevent ext4 from incorrectly mounting the same image twice. It would also allow rbd map to let the user specify a name for the rbd image mapping.
The current behavior is useful in some cases, however. Probably there should be a --force-duplicate option to force a new kernel mapping as in the current behavior.
