| I have tryed to create optimized Dapper Desktop CD ISO which supports
| readahead and some other improvements to shorten boot time.

readahead is explicitly disabled on the Dapper desktop CDs due to it
interacting badly with squashfs and unionfs.  JFYI.

| This CD boots up in 1:09 with my PC and works fine. The normal Desktop
| CD boots up in 2:24 with same PC.

Nice.

| Test results and any feedbacks will be helpful.

The idea of running multiple scripts from casper-bottom in parallell
is interesting.  I'll look more into that when I get back from
vacation.
