That is a really old tutorial. The official instructions are in
/usr/share/doc/mandos-client/README.Debian.gz. What version of Mandos
are you using? We always suggest to use the latest version from our
official repository, as documented here:

It is not intended for it to be necessary to alter /etc/crypttab; there
are scripts run at boot to insert plugin-runner as the keyscript.
Therefore, if you add your own keyscript setting, this will take
precedence, and prevent the automatic keyscript setting from working
correctly.

I am guessing that this is because the location of the plugin-runner
binary has changed since that old tutorial. It is now *not* located
directly under /usr/lib/mandos, but instead in the architecture-specific
directory below /usr/lib. But, again, you should not need to care about
this, since it should all be done automatically.

Why are you adding things to /etc/crypttab? What happens if you do not?
It should work fine without it.

Yes. Simply set the "checker" setting in /etc/mandos/clients.conf to
a command which does nothing, like this:
checker = :
