Systemd

Description

systemd is a system and session manager for Linux also including udev nowadays.

Kernel settings

First of all you need a recent kernel version >=3.8 and some kernel options set.

Installation

File: /etc/paludis/options.conf

*/* build_options: jobs=5 -recommended_tests
*/* systemd
sys-apps/systemd simple-net

# cave resolve systemd -x

Now we need to reinstall packages with the systemd option set.

# cave resolve world -cx

Network

You can find out what the network device will be named by running:

# udevadm test-builtin net_id /sys/class/net/<ifname> 2> /dev/null

Code: network device name

ID_NET_NAME_MAC=enx005056a84955 ID_NET_NAME_PATH=enp11s0

systemd-networkd

File: /etc/systemd/network/eno1.network

[Match]
Name=eno1

[Network]
DHCP=0
Address=192.168.0.88/24
Gateway=192.168.0.1

NetworkManager

# cave resolve repository/desktop -x

# cave resolve NetworkManager -x

# systemctl enable NetworkManager.service

NetworkManager does DHCP by default.

Enable sshd connectivity

# systemctl enable sshd.socket

# systemctl start sshd.socket

Configuration

Hostname

Edits /etc/hostname and /etc/machine-info.

# hostnamectl set-hostname desiredhostname

Timezone

Sets the /etc/localtime symlink.

# timedatectl set-timezone Europe/Berlin

Keyboard Layout

Edits /etc/vconsole.conf.

# localectl set-keymap de

Localization

Edits /etc/locale.conf.

# localectl set-locale LANG="en_US.utf8"

The systemd localectl commands sets the system locale, if you want to set you user locale use /etc/env.d/02locale.

Misc

Manually starting and stopping services

You'll find an overview of all installed services and sockets in /lib/systemd/system.

# systemctl start <service>.service

# systemctl stop <service>.service

# systemctl

prints a status report of your systemd setup.
