Systemd

Description

systemd is a system and session manager for Linux.

Kernel settings

First of all you need a recent kernel version >=2.6.39 and some kernel options set.

Linux Kernel Configuration: Kernel .config

General setup ---> [*] Control Group support ---> [*] Namespace cgroup subsystem [*] Freezer cgroup subsystem [*] Device controller for cgroups [*] Simple CPU accounting cgroup subsystem [*] Group CPU scheduler ---> [*] Group scheduling for SCHED_OTHER <*> Block IO controller Device Drivers ---> Generic Driver Options ---> [*] Maintain a devtmpfs filesystem to mount at /dev [*] Automount devtmpfs at /dev, after the kernel mounted the rootfs File systems ---> [*] Filesystem wide access notification [*] fanotify permissions checking < > Kernel automounter support <*> Kernel automounter version 4 support (also supports v3) Security options ---> [*] Enable different security models

Paludis configuration

Unmask currently masked packages

File: /etc/paludis/package_unmask.conf

dev-lang/vala
dev-libs/glib

System and package options

File: /etc/paludis/options.conf

*/* build_options: -recommended_tests
*/* systemd
sys-apps/systemd simple-net

First we need to add repositories for the dependencies not in ::arbor (you need to setup Paludis for automatic repository installation first).

# cave resolve repository/desktop repository/x11 -x

Install the systemd package:

# cave resolve systemd -x

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

# cave resolve world -c -x

Swich over to systemd using eclectic.

# eclectic init set systemd

Reboot and login.

Enable network

either for simple net:

# systemctl enable network.service

or when using NetworkManager:

# systemctl enable NetworkManager.service

Enable sshd connectivity

# systemctl enable sshd.socket

Reboot and login via SSH.

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.

Enable additional/optional services

vixie-cron:

# systemctl enable vixie-cron.service

ntp:

# systemctl enable ntpd.service

# systemctl enable mysql.service
