Command create .. from mirror makes persistent immutable snapshot of remote repository mirror. Snapshot could be
published or further modified using merge, pull and other aptly features.
Command create .. from repo makes persistent immutable snapshot of local repository. Snapshot could be processed
as mirror snapshots, and mixed with snapshots of remote mirrors.
Command create .. empty creates empty snapshot that could be used as a basis for snapshot pull operations, for example.
As snapshots are immutable, creating one empty snapshot should be enough.
