Chapter 19. Concurrent Versioning System

The Concurrent Versioning System (CVS) is a free revision-control system. It is used to monitor and keep track of modifications to a central set of files which are usually accessed by several different users. It is commonly used by programmers to manage a source code repository and is widely used by open source developers.
In Red Hat Enterprise Linux, the cvs package provides CVS. Enter the following command to see if the cvs package is installed:
~]$ rpm -q cvs
package cvs is not installed
If it is not installed and you want to use CVS, use the yum utility as root to install it:
~]# yum install cvs

19.1. CVS and SELinux

The cvs daemon runs labeled with the cvs_t type. By default in Red Hat Enterprise Linux, CVS is only allowed to read and write certain directories. The label cvs_data_t defines which areas cvs has read and write access to. When using CVS with SELinux, assigning the correct label is essential for clients to have full access to the area reserved for CVS data.
