Subversion

I can't think of anything specific to Mercury that would effect adding subversion to your server. BZR would be another option, and the client is already installed on the server.

One to note is this: /var/lib/bcfg2 and /var/www/profiles is already under version control so that you can easily download updates from launchpad if you wish (using the /usr/local/bin/update_mercury.sh script. Also, /var/www (ie, pressflow) is under version control for the same reasons (this can be updated with /usr/local/bin/update_pressflow.sh). I'm not a svn guru and don't know what the result would be if you then tried to add these to local version control but my guess is the worst would be that you would no longer be able to update from launchpad.
