SVN for /etc
Subversion also known as SVN is a version control system. Normally users 'checkout' data from a central repository to a local 'working copy'. However it can be setup to allow version control for files /etc .
sudo svnadmin create /svn sudo chmod -R go-rwx /svn/ sudo svn mkdir file:///svn/etc -m"creating empty dir for svn" cd /etc sudo svn checkout file:///svn/etc . sudo rm -R .svn/ sudo svn checkout file:///svn/etc . sudo svn add * sudo svn commit -m"initial commit of /etc"This creates an SVN repository /svn/etc with the working copy being /etc itself. Edit files as would be done normally and 'commit' them to the repository to allow them to be version-controlled:
sudo svn commit fileTo revert a file back to a previous revision for instance:
sudo svn update -r 2 hosts
