After installing Symantec Endpoint Protection agent for Linux, customization of /etc/selinux/targeted/contexts/files/file_contexts.local is lost.
The installer for the Symantec Endpoint Protection agent for Linux version equal to or less than 14.3 RU5 is missing logic needed to preserve the contents of /etc/selinux/targeted/contexts/files/file_contexts.local after product installation.
This issue is resolved in Symantec Endpoint Protection version 14.3 RU6.
