Debian Jessie

Debian Jessie installation Notes:

Add

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

to /etc/default/grub. Then update with
```
 sudo update-grub
 sudo update-grub2
 sudo reboot
```
Add the backports which contain Systemd 2.30 and update Systemd.

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

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

Install Jinja2 and Python-Netaddr

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