====== Week - 12 ======
===== 10-11 Aug =====
  - Worked on testing and fixing small bugs in debian over iscsi
  - Tests show that it works fine as long as the round trip delay is within some bounds, else it throws ''connection timeout'' errors
  - The performance comparison between httpfs and iscsi show that iscsi is 3x faster.
  - Received the patch for pxelinux.0 from rwrc which will pass ''dns'' entry  to kernel.

===== 12-13 Aug =====
  - Getting ubuntu boot over iscsi
  - Added rescue shell option to debian. 
    - This option can be activated by appending keyword ''rescuebreak'' in kernel parameters
    - It will give you ''sh'' shell when it is done with mounting root partition.  
    - This option is primarily for developers who want to explore the invironment at this stage of booting.
    - When user is done with this exploration, he/she can use ''exit'' command to continue the normal boot process.
  - Added rescue shell to Ubantu also,
    - But this did not worked well as Ubuntu initramfs does something wired with standard intput and output that I dont understand :-(
    - Even simple echo statements don't come on the console.
    - There are some ''log_begin_msg'', ''log_end_msg'' functions that are used in initramfs, but I have not yet properly explored them, So I dont know how they work.


===== 14 Aug =====
  - Adding knoppix-6 to BKO
    - I tried for knoppix-6 DVD as warthog had suggested, but DVD version is available only for knoppix-5. I am not sure if that version will use ''cpio'', so planning to stick with Knoppix-6 CD version.
    - First, knoppix-6 booting with ''httpfs'' will be added.
    - Then it will be extended to ''iscsifs'' support.
