By | 2014/10/20

For Debian Wheezy, switching to systemd is easy. Here’s the scoop!

1. First, add the wheezy-backports repository to your /etc/apt/sources.list file:

deb wheezy-backports main contrib non-free

2. Refresh packages available:

$ sudo apt-get update

3. Install systemd:

$ sudo apt-get -t wheezy-backports install systemd

The output will look similar to the following:

smiller@bruckner:~$ sudo apt-get -t wheezy-backports install systemd

4. Add your user to the group systemd-journal so you can run journalctl commands without sudo:

smiller@bruckner:~$ sudo gpasswd -a smiller systemd-journal
Adding user smiller to group systemd-journal

5. Make sure /sbin/init is linked to systemd (a Debian thing) as a quick check before rebooting:

$ ls -l /sbin/init 
lrwxrwxrwx 1 root root 20 Jul  5 08:33 /sbin/init -> /lib/systemd/systemd

6. Reboot!

$ sudo reboot

    You need to also install systemd-sysv in order to link /sbin/init to /lib/systemd/systemd
