Installing yaVDR

Install from USB stick

Boot from the USB stick. Scroll down and select SGD: Super Grub Disk.

root (fd1)
loopback lb ($root)/yavdr-0.3a.iso
root (lb)
linux (lb)/install/vmlinuz
append  file=/cdrom/preseed/yavdr-s2.seed localechooser/translation/warn-light=true localechooser/translation/warn-severe=true 
initrd (lb)/install/initrd.gz
boot

Now the setup should start and complains about a missing CD, start the console:

mkdir /mnt/usbstick
mount /dev/sdb /mnt/usbstick
losetup /dev/loop0 /mnt/usbstick/yavdr-0.3.0a.iso
CTRL+D

Continue the installation select auto, then no, then yes and enter as manual cd-device /dev/loop0.

Using PXE to run yaVDR

At first install yaVDR by using the normal ISO. I installed it on a virtual machine in Parallels.

After that is finished and the installation boots fine we have to copy the complete installation to our server. To do this, login into your yaVDR, upgrade the system with:

apt-get update
apt-get upgrade
apt-get install s2-liplianin-dkms

Edit the file /etc/initramfs-tools/initramfs.conf:

MODULES=netboot
BOOT=nfs

Edit the file /etc/network/interfaces:

auto lo
iface lo inet loopback

iface eth0 inet manual

Edit the file /etc/resolve.conf:

nameserver 192.168.0.251

Edit the file /etc/fstab;

proc            /proc           proc   nodev,noexec,nosuid 0       0
/dev/nfs        /               nfs    defaults         0       1

Create the initramfs newly with:

mkinitramfs -o /boot/initrd.img-2.6.32-27-nfs

At first we pack the complete tree:

cd /
tar cjvf yavdr-0.0.3.tar.bz2 --exclude=proc --exclude=sys --exclude=yavdr-0.0.3.tar.bz2 *

Now we copy the archive to the server:

scp yavdr-0.0.3.tar.bz2 video:/yavdr

Now we extract the file and do some cleanup

cd /yavdr
tar xjvf yavdr-0.0.3.tar.bz2
mkdir proc
mkdir sys

Now we setup a aufs file structure. Our base image is now on /yavdr.

We create a new folder structure to hold our changed files per host.

mkdir /usr/local/videos/
cd !$
mkdir schlafzimmer
mkdir wohnzimmer

Now we create the folders which are mounted via NFS:

mkdir /usr/local/nfsmounts
cd !$
mkdir schlafzimmer
mkdir wohnzimmer

We can test if everything works like expected with:

mount -t aufs -o br:/usr/local/videos/schlafzimmer=rw:/yavdr=ro none schlafzimmer/

Now we add the following lines to our /etc/fstab:

# our aufs mounts
none    /usr/local/nfsmounts/schlafzimmer       aufs    br=/usr/local/videos/schlafzimmer=rw:/yavdr=ro 0 0
none    /usr/local/nfsmounts/wohnzimmer         aufs    br=/usr/local/videos/wohnzimmer=rw:/yavdr=ro 0 0

Setup the pxeconfiguration by editing your config file depending on your mac address:

PROMPT 1
PROMPT 1
DEFAULT vdrhd
TIMEOUT 1

LABEL vdrhd
  MENU HIDE
  MENU LABEL ^VDRHD
  KERNEL vmlinuz-2.6.32-27-generic
  APPEND netboot=nfs nfsroot=192.168.0.149:/usr/local/nfsmounts/schlafzimmer rw initrd=initrd.img-2.6.32-27-generic-nfs vmalloc=256m noresume nohz=off acpi_enforce_resources=lax

LABEL memtest
  MENU HIDE
  MENU LABEL ^memtest86+
  KERNEL memtest.bin

If boot now our box it should start up completely with PXE.

Compile own VDR Plugins
