[osol-mktg] JavaOne OpenSolaris track submission:LiveMedia Technologies for OpenSolaris

[Sriram Popuri]

LiveMedia for OpenSolaris is an attractive and important new direction
made possible after the opening up of Solaris source code.
This was pioneered by Joerg Schilling via his SchilliX LiveCD distribution of OpenSolaris.
   Subsequently Moinak Ghosh had come out with the BeleniX LiveCD distribution that introduced several new technologies in OpenSolaris required to make LiveMedia practical and useful.
   All the modifications and new features for LiveMedia will be integrated into OpenSolaris and the future Install roadmap of SUN's Solaris Express distribution includes the Live distro format. The Solaris Express Install DVD will be a Live bootable DVD with an install option.

   In addition LiveMedia make various other things possible, like product trial CDs,
system recovery CDs, system test CDs, system in a pocket using USB media etc.

The LiveMedia technologies umbrella project is located at:
http://www.opensolaris.org/os/project/livemedia/
and concerns not only Live CDs but also other forms of Live Media like USB Keys.
This presentation talks about all the above topics including future work:

    * Details of current technologies available like:
        o Grub based CD boot
        o Ramdisk
        o On the fly decompression
        o HSFS I/O Scheduling optimizations
        o ISO Data Block reorganization algorithm using data from DTrace Toolkit and mkisofs "-sort" option.
        o Numerous tweaks and changes to bootup scripts and utilities
    * Changes for USB based live media
    * BeleniX Remastering Toolkit
    * BeleniX Harddisk Installer
    * Solaris Express LiveKit
    * Current utilization of LiveMedia possibilities in SUN
    * What futher work needs to be done like:
        o UnionFS
        o Multisession DVDs (Similar to Puppy Linux)
        o Preserving sessions when booting off USB keys
        o Encrypting sessions
        o OpenSolaris recovery toolkit
        o Ability to use Linux swap without corrupting it
        o Dump CD to RAM
