Ken, Urs, et al.,
Thanks for the comments!
Re: the CERN Howto, one can get to it via the scientificlinux.org
home page by clicking on "Scientific Linux Live CD/DVD 4.8" in the
far left column, under "news".
On that page, scroll down to the very end and you'll see a link to
More information can be found at http://www.livecd.ethz.ch
On that page, you will see a link to "Read how to build your own
LiveCD.", which will take you here in case you don't want to go
thru all that. :-)
