In this lesson: https://app.itpro.tv/course/lpic1-linux-administrator-101500/managing-servicessystemd-lpic1 , at 15:41, Don shows his service's unit file and a "[Install]" section. There is a WantedBy=multi-user.target key-value pair.
Is this really required when we enable the service and the symbolic link is created? What is the purpose of the Install section and the WantedBy key? Does setting this here allow the "systemctl enable" to work and do they work together or is it redundant? Thanks.
