* User Stories
** yavdr-full
A User wants to install yaVDR without customization and relies on full automation.

After installing a supported Ubuntu Server version and (if needed) setting up the network connection, the install script is downloaded and started.

The install script adds the ansible PPA, installs ansible and other basic dependencies and runs the automated installation process.

Several roles are used to tie everything together:
- yavdr-common :: installs the basic set of packages needed and preconfigures the system (package sources, package manager settings, entires for network ports, directory structure etc.). Also collects information about the system
- autoinstall-ubuntu-drivers :: uses Ubuntu's automatic detection for additional drivers (e.g. proprietary nvidia driver, microcode updates, VirtualBox guest additions)
- vdr :: install the vdr package and required plugins
- pulseaudio :: install and preconfigure pulseaudio
- yavdr-network :: configure WOL, add nfs client capabilites, install avahi-linker
- samba-server :: install and preconfigure a samba server
- nfs-server :: install nfs-kernelserver and preconfigure nfs exports (and avahi-announcements)
- autoinstall-satip :: install vdr-plugin-satip if a Sat>IP server has been found
- autoinstall-targavfd :: install vdr-plugin-targavfd if display is connected
- autoinstall-imonlcd :: install vdr-plugin-imonlcd if a matchind display is connected
- yavdr-xorg :: install and configure a systemd user session with a running X-server.  A frontend script will manage VDR's frontend and other applications like KODI.  Also choose the best possible output plugin.
- grub-config :: update grub configuration based on executed roles

*** NVIDIA-Documentation about the BusID:
**** What is the format of a PCI Bus ID?
Different tools have different formats for the PCI Bus ID of a PCI device.

The X server's "BusID" X configuration file option interprets the BusID string in the format "bus@domain:device:function" (the "@domain" portion is only needed if the PCI domain is non-zero), in decimal. More specifically,

"%d@%d:%d:%d", bus, domain, device, function
in printf(3) syntax. NVIDIA X driver logging, nvidia-xconfig, and nvidia-settings match the X configuration file BusID convention.

The lspci(8) utility, in contrast, reports the PCI BusID of a PCI device in the format "domain:bus:device.function", printing the values in hexadecimal. More specifically,

"%04x:%02x:%02x.%x", domain, bus, device, function
in printf(3) syntax. The "Bus Location" reported in the /proc/driver/nvidia/gpus/0..N/information files matches the lspci format.

* Introduction
One of the major problems we faced with customized Ubuntu ISO files as installation media for prior yaVDR versions has been the limited hardware support and the time consuming process to create and update them.  An interesting alternative to this approach is to enable the user to choose the installation medium by himself, so point releases, kernel versions and additional drivers can be chosen deliberately.  After the basic setup is complete (and a working internet connection is available), a fully customizable install script completes the yaVDR installation.
* Installing and configuring yaVDR with Ansible
This is an experimental feature which allows to set up a yaVDR installation based on a normal Ubuntu Server 16.04.x installation using [[http://ansible.com][Ansible]].

This Manual is written in org-mode for Emacs and can rewrite the complete ansible configuration if you call ~org-babel-tangle~ from within emacs.

To use this playbook on a Ubuntu Server Installation you need to run the following commands:
#+BEGIN_SRC shell
sudo apt-get install git
git clone https://github.com/yavdr/yavdr-ansible.git
cd yavdr-ansible
git checkout bionic
sudo ./install-yavdr.sh
#+END_SRC

We use a callback to generate tags for all roles autmatically:
#+INCLUDE: "ansible.cfg" src conf

** Install script for local usage
#+BEGIN_SRC shell :tangle install-yavdr.sh :shebang "#!/bin/bash"
if (( $EUID != 0 )); then
    echo "This script must be run using sudo -H or as root"
    exit
fi

apt-get -y install software-properties-common
# update packages
apt-get update
# install required packages
apt-get -y install --no-install-recommends ansible

# Keymaps table
#
# This table creates an association between a keycode file and a kernel
# driver. It can be used to automatically override a keycode definition.
#
# Although not yet tested, it is mented to be added at udev.
#
# To use, you just need to run:
#	./ir-keytable -a
#
# Or, if the remote is not the first device:
#	./ir-keytable -a -s rc1		# for RC at rc1
#

# Format:
#	driver - name of the driver provided via uevent - use * for any driver
#	table -  RC keymap table, provided via uevent - use * for any table
#	file - file name. If directory is not specified, it will default to
#		/etc/rc_keymaps.
# For example:
# driver	table				file
# cx8800	*				./keycodes/rc5_hauppauge_new
# *		rc-avermedia-m135a-rm-jx	./keycodes/kworld_315u
# saa7134	rc-avermedia-m135a-rm-jx	./keycodes/keycodes/nec_terratec_cinergy_xs
# em28xx	*				./keycodes/kworld_315u
# *		*				./keycodes/rc5_hauppauge_new

# Table to automatically load the rc maps for the bundled IR's provided with the
# devices supported by the linux kernel

** yavdr-xorg
*** About the GUI session
The X-Server is started by using the two systemd units ~xlogin@.service~ and ~x@.service~ provided by the package *xlogin*.  The former is enabled (and started) for the vdr user - which results (using the default settings for the user *vdr* with the uid *666*) in the activation of ~xlogin@vdr.service~ when reaching the graphical.target. To simplify starting and stopping the X-server and the desktop session a ~yavdr-xorg.service~ is provided by the package ~yavdr-xorg~, which depends on the two units mentioned before.

~x@vt7.service~ is started automatically as a dependency of ~xlogin@vdr.service~ and starts the X-server.  ~xlogin@vdr.service~ also starts a systemd user session using ~user@666.service~.
In order to use the keyboard layout configured during installation for the X-Server the script ~write-x11-keyboard-config~ reads the keyboard configuration from ~/etc/default/keyboard~ when starting ~x@.service~ and writes the file ~/etc/X11/xorg.conf.d/00-keyboard.conf~ (because systemd for Ubuntu (and Debian) has been patched not to create ~/etc/X11/xorg.conf.d/00-keyboard.conf~ according to the ~localectl~ settings). 

To prevent stopping the X-server when vdr is running, additional dependencies are set up - see the drop-in rules created in ~/etc/systemd/system/vdr.service.d/~.

Basic Services like the session DBus, pulseaudio etc. are started for the ~default.target~ of the session.
The openbox autostart script is used to update the systemd session with the needed session variables.  It creates a file =~/.session-env= which is used as an environment file by ~vdr.service~ (so the vdr knows the *DISPLAY* and can access pulseaudio).

The autostart script then enables all services to be pulled in by yavdr-desktop.target.  As the last step ~yavdr-desktop.target~ is startet, which results in staring ~yavdr-frontend.service~ and additional Units for a second display (openbox and a browser for osd2eb, if available).

# TODO: describe yavdr-frontend

In order to achive a clean shutdown of the session, ~x@t7.service~ is set as a dependency of the systemd unit instance ~user@666.service~ and all processes within the session must be shutdown properly when stopping ~xlogin@vdr.service~.  If systemd units are used within the user session, they must stop their process(es) successfully (you should set them up to accept expected exit codes appropriately).  The window manager /openbox/ is started using the =~/.xinitrc= and stopped using the systemd unit ~exit-wm.service~ (which runs on stopping the jobs pulled in by the ~default.target~ of the session).

# Cap the size of the individual log files (in KiB).
   max log size = 1000

# We want Samba to log a minimum amount of information to syslog. Everything

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
   unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes

# 'passwd program'. The default is 'no'.
