             ##### `TIMEZONE`="Europe/Berlin"
             Set default system timezone. All available timezones can be found in the `/usr/share/zoneinfo/` directory. This setting can also be changed inside the running OS using the `dpkg-reconfigure tzdata` command.
+            ##### `EXPANDROOT`=true
+            Expand the root partition and filesystem automatically on first boot.
             #### Keyboard settings:
             These options are used to configure keyboard layout in `/etc/default/keyboard` for console and Xorg. These settings can also be changed inside the running OS using the `dpkg-reconfigure keyboard-configuration` command.
             ##### `XKBMODEL`=""
             ##### `ENABLE_SSHD`=true
             Install and enable OpenSSH service. The default configuration of the service doesn't allow `root` to login. Please use the user `pi` instead and `su -` or `sudo` to execute commands as root.
+            ##### `ENABLE_RSYSLOG`=true
+            If set to false, disable and uninstall rsyslog (so logs will be available only
+            in journal files)
             ##### `ENABLE_SOUND`=true
             Enable sound hardware and install Advanced Linux Sound Architecture.
             ##### `ENABLE_IPTABLES`=false
             Enable iptables IPv4/IPv6 firewall. Simplified ruleset: Allow all outgoing connections. Block all incoming connections except to OpenSSH service.
+            ##### `ENABLE_USER`=true
+            Create pi user with password raspberry
+            ##### `ENABLE_ROOT`=true
+            Set root user password so root login will be enabled
+            ##### `ENABLE_ROOT_SSH`=true
+            Enable password root login via SSH. May be a security risk with default
+            password, use only in trusted environments.
             ##### `ENABLE_HARDNET`=false
             Enable IPv4/IPv6 network stack hardening settings.
