This means that the accesslist.log will contain the messages printed out by the monitor module to /proc/kmsg.

- Start all needed programs.

The script will only optimize open programs?

The script will only optimise the files which are accessed while the monitor is running.

- rmmod monitor # stop monitor

I guess type it in just like that from a root shell?

just type in "rmmod monitor"

- killall cat # "kill the cat"

fine I don't care much for cats type that into the root shell as well?

yep, just type "killall cat" of course if you have any other background jobs running with cat they will be killed aswell! Basically this is stopping the process which was > /ramdisk/accesslist.log

/KNOPPIX.build/Knoppix.mksortlist2

Thats great! how do I use it to optimize my remaster?

Well Knoppers build scripts use a sortlist to build the cloop, presumably this will generate the correct format for those scripts!
