It's too easy to accidentally delete a container rather than a snapshot

[Rod Smith]

The command to delete a container is:

lxc delete {container}/{snapshot}

Unfortunately, if the "/" is omitted, this command deletes {container} without any sort of prompting. It would be very helpful to add a prompt/verification when deleting the entire container to avoid mishaps. Don't ask me how I know that they happen.

[Stéphane Graber (stgraber)]

There is configurable prompting for those that want it. We also refuse to delete running containers.
