I can do apt-get remove useless.package (for my usage) all works fine, the system says to me that the package is removed. But I notice 2 things:
- after that the useless.package has been removed the memory free is

   smaller than before.
- I stop the computer and when I reboot the box the useless.package is

   always there. I think it has been removed of the ramdisk not of the USB    stick.
  I used "Knoppix Persistent feature" ... but nothing persist ...   I think that I also miss something as well.
