Also, compare this one

ln -s /lib/systemd/system/ifupdown@.service
/etc/systemd/system/multi-user.target.wants/ifupdown@enp2s1.service

with systemctl enable ifupdown@enp2s1

This is even simple one. There are more complicated units like:

systemctl enable NetworkManager

ln -s '/lib/systemd/system/NetworkManager.service'
'/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service'
ln -s '/lib/systemd/system/NetworkManager.service'
'/etc/systemd/system/multi-user.target.wants/NetworkManager.service'
ln -s '/lib/systemd/system/NetworkManager-dispatcher.service'
'/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service'

One short command beats 4 of them.
