I deploy my masterfiles to all hosts as Solaris packages through a corporate release process (i.e. no policy host). I have also been concerned about a similar scenario, mainly what would happen if cf-agent ran while the package was only partially installed - or if the package started to be removed mid-way through a cf-agent run. I do 2 things to mitigate this concern: 1) Get cf-agent to check for the "fully installed" package before running - and set an abortclass class if it is not. 2) Use a pre-remove script inside the package itself to check if cf-agent is running - aborting the package remove if it is. You may want to use similar concepts in dealing with subversion (pre-update hooks?) to prevent the repo being updated if cf-agent is running.
