1.4.6 Modifying a Full DVD Image to Support Btrfs root File System Installation

Note

This procedure assumes that you have set up the system as a network installation server that uses HTTP or NFS to server files.

To set up a network installation server that allows the installation of a system with a btrfs root file system:

  1. Download the full Oracle Linux Media Pack DVD image (for example, V52218-01.iso for x86_64 (64 bit) Oracle Linux Release 6 Update 6) from the Oracle Software Delivery Cloud at https://edelivery.oracle.com/linux and copy its contents to a suitable directory such as /var/www/html/OSimage/OL6.6_UEK/images or /var/OSimage/OL6.6_UEK/images, whose contents are shareable using NFS or HTTP. See Section 1.4.5, “Setting up a Network Installation Server”.

  2. Modify the images directory of the image to support the Unbreakable Enterprise Kernel (UEK) as the installation kernel:

    1. Download the UEK Boot ISO image for the desired architecture (for example, V52220-01.iso for x86_64 (64 bit)).

    2. Mount the UEK Boot ISO image:

      # mount -t iso9660 -o loop V52220-01.iso /mnt

    3. Replace the contents of the images directory that you copied from the full DVD image with the contents of the images directory from the UEK Boot ISO image.

      For example, to replace /var/OSimage/OL6.6_UEK/images:

      # rm -rf /var/OSimage/OL6.6_UEK/images
      # cp -r /mnt/images /var/OSimage/OL6.6_UEK

      To replace /var/www/html/OSimage/OL6.6_UEK/images:

      # rm -rf /var/www/html/OSimage/OL6.6_UEK/images
      # cp -r /mnt/images /var/www/html/OSimage/OL6.6_UEK

  3. Copy the UEK Boot ISO image to a suitable medium from which you can boot the target system on which you want to install Oracle Linux 6 Update 6.

  4. Unmount the UEK Boot ISO image:

    # umount mount_dir

You can now use the modified image to install a system with a btrfs root file system. See Section 2.4.1, “Installing a Btrfs root File System”.
