Version control lets us track files over time. Nets old standard was CVS, today subversion is the standard. The GIT solution has been evaluated but is not formally approved by the architect forum. It is also important to note that Novell (yes we are using SLES Linux) at this moment does not support GIT packages. It's possible to download GIT packages from kernel.org and from Novell’s build cluster (software.opensuse.org).
CVS has been used longer than subversion, and no new projects are using CVS. Nevertheless you will see that the CVS disk footprint still is the biggest part.
Operation developers use subversion in some projects (where subversion/svn has been installed) running their scripts on the different NFS file servers. The code from the operation developers is also included with common source code tree.
