	Network configuration in Void Linux can be done in several ways. The default

	service enabled.

"The default installation" is weird and confusing, there is no a real default installation and if there is (xbps-install -r /mnt base-system) then dhcpcd is not enabled, this should probably be fully removed or reworded to say that dhcpcd may be installed depending on the ISO and the installation method.
