Unclear 'sudo mailinabox' command for maintenance

[User1000001]

The maintenance page instructs at the end of the 'Moving to a New Box / Testing Backups' part to re-run the setup:

Re-run Mail-in-a-Box setup now that your old files are back:
`sudo mailinabox`

It is unclear what the sudo mailinabox is supposed to do. On my setup, there is no executable 'mailinabox'.
Is it supposed to be sudo mailinabox/setup/start.sh?

If you have already installed mail-in-a-box before, there will be a mailinabox file:

@box:~$ which mailinabox
/usr/local/bin/mailinabox

the contents of that file are very much like your last line.
