amorphous version control for configuration files

[David Nicol]

is anyone using mercurial to manage configuration files?  The everything's-a-tip
version control paradigm seems like it would be really good for
managing configurations;
check out a configuration close to what you want, warp it a little,
check it back in
and keep track of the node and its branch by naming the branch after the node's
host name.
