Newbie Updating Question

[Stephen A. Witt]

I read where FAI is used to both "install" and "update" a Debian
installation. I sort of understand the installation part (well, I'm
working on it), but I don't understand the update part, unless update
means reinstall with an updated FAI configuration. It seems that when
updating you'd fall back on the normal Debian dselect/apt-get update
mechanisms, or is there something that does this in FAI that I'm missing.

Thanks...
