Speed up CD/DVD-based FreeBSD

[O. Hartmann]

We have a special case of running FreeBSD (actually a NanoBSD) from a CD/DVD.
The reason behind using a CD/DVD is to prevent manipulations.

Now, after the GUI hass started, the system autologin a user and autostarts
Firefox. But starting Firefox takes ~ 5 - 7 minutes, while the operating system
takes 2 - 3 minutes. As you can imagine, this isn't quite a useful time.

Is there a simple way, considering enough RAM in the box, to speed up the
process? Loading Firefox makes the DVD drive moving the head very often - I
assume this is the fact because I can hear the head scratiching around very
intense.

Does FreeBSD bring tools/facilities onboard to achive what I'm requesting or do
I need an additional port/softwarepackage?

Any considerations are welcome.

Thanks in advance,

Oliver
