With so many folks carrying around powerful laptops these days, how about
doing a VM InstallFest: teach how to install Linux into a VM as practice.
 While this would not cover (the most important) topics of getting
non-standard hardware/software working, it might at least give people
confidence in basic installation skills.  (Practical consideration: it
might be wise to setup an Apt-Cacher NG local proxy, loading the cache
before the event, in order to make the installation faster as well as
significantly reduce network usage.)

Changing the /boot/grub/grub.conf configuration file directly would likely
result in a change that works for a short time and is then lost with a
system update (anything that changes that file, such as a new kernel).  On
most distributions, one does not change /boot/grub/grub.conf directly; on
Debian, change /etc/default/grub instead, and then run `sudo update-grub`
(as documented in the file comments) to apply the changes.
