Well, I think I've been taken out of context so let me just say this
suggestion goes along with a plan that would reduce the freeze time to a
few weeks. There should also be more communication between the mirrors
alerting them to any change that will cause lots of bandwidth or hd space.
Random thought, perhaps reversing the sym links for a freeze would work,
no extra space, but a bit of bandwidth. Anyway, it's all irrelevant since
my message was only so it would be on the record for future use and wasn't
intended to make any changes to the current system. Let's give Richard a
chance, I think he'll make some improvements (assuming he does take
Brian's place).

This would be nice, but what about those other mirrors that wouldn't have
hard link capabilities (insist on making a mirror via ftp). I guess
they'd just suffer with multiple copies. It's problems like yours that
make me think we'll end up breaking the ftp archive into multiple parts
one day. Scalability and centralization don't work very well together.
