config scripts are supplied. but along with the lab instructions,
a hints page is provided......the explanations are not in depth
at all...which is partly why Id like to summarize my notes on
the labs...and see if others are in agreement.

Folks,
What is the depth of the explanations of the "gotchas" in these
scenarios.
In other words, is the solution just a config script, or do the authors
go
into some detail.
Thanks,
Bob
