vultr doesn't let you shut down a server while it's creating a snapshot. however, it *did* let me run "shutdown now", which shuts down the server, and *then* start creating the snapshot.
i hope my snapshot doesn't get corrupted or anything... it takes quite a while to create one, and i really don't know how long it's going to take. i've been leaving the console window open waiting for it to be ready, but there's no progress bar or anything.
honestly, i'm pretty scared right now.
