In latptops/workstations NetworkManager takes care of everything. However, I still enable systemd-networkd and systemd-resolved in my laptop and workstations. If enabled without any configuration, it just monitors the network interfaces and keeps them "in the loop" for the rest of the system to know about them from a central registry. It doesn't interfere with NetworkManager (or any other network management program for that matter). It's not mandatory to enable them either. However, there were advantages to doing so; for example, in my laptop, systemd-timesyncd would try to sync the clock only if there was a network connection available.

In latptops/workstations NetworkManage= r takes care of everything. However, I still enable systemd-networkd and sy= stemd-resolved in my laptop and workstations. If enabled without any config= uration, it just monitors the network interfaces and keeps them "in th= e loop" for the rest of the system to know about them from a central r= egistry. It doesn't interfere with NetworkManager (or any other network= management program for that matter).

It's not manda= tory to enable them either. However, there were advantages to doing so; for= example, in my laptop, systemd-timesyncd would try to sync the clock only = if there was a network connection available.
