Error: unknown command "start" for "cosmovisor"

[mightywomble]

Following on from #6 I've taken your advice and am building my own testnet server, I found the one liner

source <(curl -sL https://get.osmosis.zone/run)

I've run this, run through the script, chose the defaults in every case (except for choosing testnet, not mainnet), downloaded the 63Gb snapshot, and this morning I've got a pretty screen asking me to run

The script ends with

Please run sudo systemctl start cosmovisor
(or words to the effect)

Which i did, and it errors, why does it error I hear you ask

Error: unknown command "start" for "cosmovisor"

An investigation of

/lib/systemd/system/cosmovisor.service

shows that the service is trying to execute

ExecStart=/usr/local/bin/cosmovisor start --home /home/david/.osmosisd

Nothing funky there for sure?

I run

/usr/local/bin/cosmovisor --help

and behold

Usage:
  cosmovisor [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  init        Initializes a cosmovisor daemon home directory.
  run         Run an APP command.
  version     Prints the version of Cosmovisor.

No start function

So I'm left with 2 choices

1. The 1 liner doesn't work, and no one bothered to test it (I doubt)
2. The 1 liner has pulled a new version of cosmovisor which doesn't have a start command?

Any suggestions? The one liner is pretty jailed so its almost impossible to do the wrong thing..
