X11/KDE startup file accesses

[Skunk Worx]

Hi,

I'm using fedora core 4, with the KDE desktop. Suppose I am in runlevel 
3, and run "startx". I would like to have a list of all files accessed 
between those two points in time.

I have tried (as root) lsof with "-u root" and "+r1" to a file, but it 
does not appear to catch all the files accessed.

Here is my specific problem:

-I am using the Kadischi Fedora livecd project to create a bootable DVD.
-Kadischi uses the mkzftree method of compression
-the DVDs boot into console mode or X11/KDE based on the system environment.
-the time between console mode and actually getting to the desktop is 
about four minutes. The DVD light is flashing like crazy during this period.
-so far I have put most of the X11R6/KDE libs and binaries in ramdisk 
but this only drops about 30 seconds off the display startup.
-i'd like to cache/preload whatever is getting accessed during the 
desktop startup phase into a ramdisk or just cat/copy them to /dev/null 
to preload the files into the fs cache.

I guess all i'll be doing is moving the decompression earlier in the 
startup, but getting the display to come up fast without accessing the 
DVD would make the process appear faster to the users.

Comments/suggestions are appreciated.
