Hi Ken,
We're getting there! Thanks for your efforts.

I would rather remove "at least a day", it's better explained below.

Leave here a note about possible future enhancements with mirror
lists that would remove this restriction.

Another note: TODO in sysinstall: check safely for existence of
architecture in selected mirror, and ask the user another mirror (or use
the mirror lists enhancement).

My experience with this is that release dates are announced very
early, and I've never missed one, only by reading my email. I like this
part of the text.
BTW, this remember me something that probably belongs here: The
contents in /pub/FreeBSD/doc is constantly changing, probably because of
daily compilations of source code. I just stopped mirroring this daily,
until I find a smarter mechanism to do that. For now, it's a bandwidth
waster!
