You probably
donīt ...
... if you
only need to boot one particular computer or
several very similar machines with your Recovery CD.
However, you
will need
the
flexibility of boot profiles
to adapt
your CD on-the-fly to boot a variety of totally
different computers.
...
Including some of those old low resource boxes.
But,
if
you are happy with ONE preset boot scenario
... you may
just set ReatogoLogon to "SilentBoot" and it will
silently boot you directly up to your default shell.
