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 programmers.
In Red Hat Enterprise Linux, the cvs package provides CVS. Run the
rpm -q cvs command to see if the cvs package is installed. If it is not installed and you want to use CVS, run the following command as the root user to install it:
yum install cvs
cvs daemon runs as
cvs_t. 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 the
cvs daemon 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.
