Merging changes into the 14G planet file takes my server about an hour,
so I don't think writing an 85 byte state file at the end of it will
impact performance much.

I'm interested to know what commands you use to merge changes into a
planet file in five minutes.

However, I see that changing the symbolic link before updating the state
file is a flawed idea anyway.
