System and package options

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.

Optional services

vixie-cron:

# systemctl enable vixie-cron.service
