# Debian Jessie

Debian Jessie installation Notes:

- Add

  ```ini
  GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
  ```

  to `/etc/default/grub`. Then update with

  ```ShellSession
  sudo update-grub
  sudo update-grub2
  sudo reboot
  ```

- Add the [backports](https://backports.debian.org/Instructions/) which contain Systemd 2.30 and update Systemd.

  ```ShellSession
  apt-get -t jessie-backports install systemd
  ```

  (Necessary because the default Systemd version (2.15) does not support the "Delegate" directive in service files)

- Add the Ansible repository and install Ansible to get a proper version

  ```ShellSession
  sudo add-apt-repository ppa:ansible/ansible
  sudo apt-get update
  sudo apt-get install ansible
  ```

- Install Jinja2 and Python-Netaddr

  ```ShellSession
  sudo apt-get install python-jinja2=2.8-1~bpo8+1 python-netaddr
  ```
