I'm not concerned so much about the size of the release medium as I am
about how much space this will take on my /usr partition.  I still
remember having to resize the root partitions on all my machines when
the kernel symbols were added.  My head machine also has a small drive
with everything under / and space is very tight once all the ports are
installed.
