I tried something similar, and noticed that despite the --config-file
option, dirvish still always reads the "main" config file. The way I
worked around this, was to forget about the --config-file option and to
switch around different versions of the main config
(/etc/dirvish/master.conf); actually what happens is that master.conf is
a symlink that point to a different file depending on what day it is.
The cron job that runs dirvish also fixes up the symlink.

I wouldn't use dd... unless you're planning to copy over the entire
filesystem via the underlying block device. Use rsync or cp -a.
