Peter> You can use svk instead of svn
I do not see how this solves the metadata issue if you use a version
control system directly without the smartness etckeeper brings to the
table e.g. by using its .gitignore settings.
svk is an attempt to inject the notion of being a decentralized scm into
a centralized one (which svn happens to be) ... that has nothing to do
with putting /etc under version control
