Optimize the Linux operating system

Configure the Linux file system by making the following changes.

The server explicitly overrides environment variables like PATH, LD_LIBRARY_PATH, and LD_PRELOAD to ensure that settings used to start the server do not inadvertently impact its behavior. If these variables must be edited, set values by editing the set_environment_vars function of the lib/_script-util.sh script. Stop and restart the server for the change to take effect.
