You can use shortened UUIDs!
Example:
Instead of typing or pasting the long UUID:
iocage console f7253c38-01c7-11e4-bfd9-cc52afcf0d66
Just enter the first few characters:
iocage console f725
If multiple jails match the short name iocage will throw a warning.
You can use the short UUIDs with any subcommand.
