There used to be a saying that the highest bandwidth link between London
and Manchester was a van full of tapes. I suspect it's still true. The
obvious suggestion is to carry the initial image on tape or disk rather
than use a slow network connection. But if you don't want to do that ...

There are at least two options:

(1) simplest. Just run the initial dirvish command on the command line
instead of as a cron job. Only edit the cron file after it's finished:

  dirvish --vault your-vault --init

(2) If you really want to use a cron job for some reason, add the
command to the cron file, wait until it's started running, then comment
it out of the cron file until it's finished.
