> What would be nice might be to be able to define the prefix for /etc to something else (so we can use atomic symlink changes to flip configs).
Make /etc a symlink to /var/config/etc. Make /var/config a symlink to config-0.
Flip configs by atomically replacing the /var/config symlinks.
You'll have to move /etc, or part of it, out of the root filesystem anyway, because
you'll want to make your / read-only: so, kill two birds with one stone.

Honestly, using djbdns is almost as easy, thanks to the programmatically sane config
file formats; and it will scale better.
