wiki.archlinux.org systemd-networkd
systemd-networkd is a system daemon that manages network configurations. It detects and configures network devices as they appear;
To use systemd-networkd, start/enable systemd-networkd.service.
It is optional to also start/enable systemd-resolved.service

wiki.archlinux.org Systemd-networkd#Configuration_files
Configuration files are located in /usr/lib/systemd/network, the volatile runtime network directory /run/systemd/network and the local administration network directory /etc/systemd/network. Files in /etc/systemd/network have the highest priority.
Tip: To override a system-supplied file in /usr/lib/systemd/network in a permanent manner (i.e even after upgrade), place a file with same name in /etc/systemd/network and symlink it to /dev/null
wiki.archlinux.org Systemd-resolved#DNS
Using the systemd DNS stub file - the systemd DNS stub file /run/systemd/resolve/stub-resolv.conf contains the local stub 127.0.0.53 as the only DNS server and a list of search domains. This is the recommended mode of operation. The service users are advised to redirect the /etc/resolv.conf file to the local stub DNS resolver file /run/systemd/resolve/stub-resolv.conf managed by systemd-resolved. This propagates the systemd managed configuration to all the clients. This can be done by replacing /etc/resolv.conf with a symbolic link to the systemd stub:
ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
wiki.archlinux.org Dhcpcd
dhcpcd is a DHCP and DHCPv6 client. It is currently the most feature-rich open source DHCP client, see the home page for the full list of features.
wiki.archlinux.org Dhcpcd#Running
To start the daemon for all network interfaces, start/enable dhcpcd.service.
To start the daemon for a specific interface alone, start/enable the template unit dhcpcd@interface.service, where interface can be found with Network configuration#Listing network interfaces.
Using the template unit is recommended; see #dhcpcd and systemd network interfaces for details.
wiki.archlinux.org Dhcpcd#10-wpa_supplicant
Enable this hook by creating a symbolic link, which ensures the current version is used, even after package updates:
ln -s /usr/share/dhcpcd/hooks/10-wpa_supplicant /usr/lib/dhcpcd/dhcpcd-hooks/
The 10-wpa_supplicant hook, if enabled, automatically launches WPA supplicant on wireless interfaces. It is started only if:
no wpa_supplicant process is already listening on that interface.
a wpa_supplicant configuration file exists. dhcpcd checks
/etc/wpa_supplicant/wpa_supplicant-interface.conf
wiki.archlinux.org listing network interfaces
both wired and wireless interface names can be found via ls /sys/class/net or ip link. note that lo is the loop device and not used in making network connections.
wiki.archlinux.org WPA_supplicant
wpa_supplicant is a cross-platform supplicant with support for WEP, WPA and WPA2 (IEEE 802.11i). It is suitable for desktops, laptops and embedded systems.
Install the wpa_supplicant package, which includes the main program wpa_supplicant, the passphrase tool wpa_passphrase, and the text front-end wpa_cli.
wiki.archlinux.org WPA_supplicant#At_boot_(systemd)
The wpa_supplicant package provides multiple systemd service files:
wpa_supplicant@interface.service - accepts the interface name as an argument and starts the wpa_supplicant daemon for this interface. It reads a /etc/wpa_supplicant/wpa_supplicant-interface.conf configuration file.
wiki.archlinux.org Configuration
As explained in #Connecting with wpa_passphrase, a basic configuration file can be generated with:
wpa_passphrase MYSSID passphrase > /etc/wpa_supplicant/example.conf
This will only create a network section. A configuration file with also the ability of #Connecting with wpa_cli and some other common options may look like:
/etc/wpa_supplicant/example.conf
Giving configuration update rights to wpa_cli
ctrl_interface=/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1
AP scanning
ap_scan=1
ISO/IEC alpha2 country code in which the device is operating
country=US
network section generated by wpa_passphrase

psk=59e0d07fa4c7741797a4e394f38a5c321e3bed51d54ad5fcbd3f84bc7415d73d
}
If security is not a concern, the passphrase can also be defined in clear text in the network section by enclosing it in quotes:
psk=”passphrase”
Swap
wiki.archlinux.org Swap Partition
Swap Partition
A swap partition can be created with most GNU/Linux partitioning tools. Swap partitions are typically designated as type 82. Even though it is possible to use any partition type as swap, it is recommended to use type 82 in most cases since systemd will automatically detect it and mount it (see below).
To set up a partition as Linux swap area, the mkswap command is used. For example:
mkswap /dev/sdxy
Warning: All data on the specified partition will be lost.
To enable the device for paging:
swapon /dev/sdxy
To enable this swap partition on boot, add an entry to /etc/fstab:
UUID=device_UUID none swap defaults 0 0
where the device_UUID is the UUID of the swap space.
