## systemd --- ## Purpose Responsible for initializing and managing daemons and services ___ ### Interacting with systemd Users interact with systemd by using the systemctl package and defining unit files systemctl provides the end user access to information and control overall services, daemons, and unit files --- ## Unit Files Unit files are used to complete a default or custom service Each systems unit files are stored in the /lib/systemd/system directory If you ever wish to modify the way any given unit functions you would edit the unit file inside of /etc/systemd/system ___ ### Unit Files Continued A common use for modifying a unit file would be to start or stop a service at a desired machine state (power on, power off, user login, user logout) One major upside to this is that if your server were to ever fail, your Unit file will restart the service on reboot
