building a debian mirror

[Alex]

hey all,

as per the documentation, one must build a debian mirror in order to build the 
FAI NFSROOT.

the docs mention that a "A partial Debian mirror only for i386 architecture
for Debian 3.0 (aka woody) without the source packages needs about 5.0GB of 
disk space."

i'm just curious what do people here do for building a mirror? i'm guessing 
most people don't want to download 5 gb of packages ? i used this link to help 
me build a minimal debian mirror:

http://people.debian.org/~debacle/mirror.html

although i did have to do a bit of tweaking.

what is the preferred/recommended way of building a mirror etc?

cheers
alex.
