Can i make a CD of the Ports Collection

[Peter Ryan]

I am very new, and have been reinstalling
FreeBSD many times to clean up whatever
mess i make and start again.

I recently used cvsup to update my 
ports collection for the 4.10_RELEASE.

Now, when I reinstall, it takes much longer
because i bring in the updated ports collection
rather than the ports collection on the
install CD (which i burnt from an ISO file)

Is there some way to burn a cd (for me that
means under winXP) containing the latest 
ports collection so that I dont have to
download it each time.

Or is there a better way of installing
with the latest ports collection.

Are the ISO images updated with a new
ports collection very frequently ?

Thanks for any pointers
Peter
