doc: Add new "Networking Setup" node for the main setup options.
This should make it easier to find how to get started setting up networking. * doc/guix.texi (Networking Setup): New section. (Networking Services): Remove 'static-networking-service', 'dhcp-client-service-type', 'network-manager-service-type', 'connman-service-type', 'wicd-service', 'modem-manager-service-type', 'usb-modeswitch-service-type', and 'wpa-supplicant-service-type'.

|
||||
The @code{(gnu services networking)} module provides services to
|
||||
configure network interfaces and set up networking on your machine.
|
||||
Those services provide different ways for you to set up your machine: by
|
||||
declaring a static network configuration, by running a Dynamic Host
|
||||
Configuration Protocol (DHCP) client, or by running daemons such as
|
||||
NetworkManager and Connman that automate the whole process,
|
||||
automatically adapt to connectivity changes, and provide a high-level
|
||||
user interface.

is the DHCP client package to use, @code{isc-dhcp} by default.
|

@end defvr
|
||||
On a laptop, NetworkManager and Connman are by far the most convenient
|
||||
options, which is why the default desktop services include
|
||||
NetworkManager (@pxref{Desktop Services, @code{%desktop-services}}).
|
||||
For a server, or for a virtual machine or a container, static network
|
||||
configuration or a simple DHCP client are often more appropriate.
