   It's gonna snap quite a bit more. Yesterday I completed writing an I/O
   scheduler for hsfs, the CDROM filesystem in OpenSolaris that is also
   known as iso9660 filesystem on Linux.

   The I/O scheduler reorders I/O requests and combines adjacent requests
   into a single one. On initial testing I am seeing a 20 second 
reduction in
   boot time. So Xfce boot takes 1 min 40 seconds on my ferrari laptop
   with network enabled. It will be faster on a desktop since the Ferrari's
   CDROM is really slow.

   I will try to explain this in layman's terms in the next Bosug meet. For
   now I can say that this I/O scheduler implements C-LOOK + deadline
   + I/O coalescing. C-LOOK is a variant of C-SCAN.

   To be fair BeleniX also needs a bunch of docs on the CD though the
   site and Wiki has docs.
