  The motivation behind this effort is to have the USB stick function like a regular hard drive and provide the basic functionality for some virtual or real machine to do exactly what it is supposed to do (and nothing much else). Again, a compressed file system would be lovely, but a plain journaled ext2 seems to allow a good start.
  
- The installation is performed via deboostrap. cdebootstrap should also work, but it has not for me. Then to be added is a bootloader. I tried with grub2, but it reads from hd0 instead of hd1 when tested on a Windows machine, and I failed to change that. If hd0 is correct for a diskless client I cannot tell. The next attempt will be with extlinux, a ext2-compatible syslinux. The following describes my current state of my attempts:

- A disadvantage of this setup is the limited space to cache the packages - the binaries eat up the disk space that is needed to unpack them. And apt-get does not care about removing packages from /var/cache/apt to free disk space during installation. After the debootstrap, one should install in fractions rather than all in one - also depending on the size of your medium. A 4GB USB stick was found far less comfy than originally anticipated. Go for at least 8GB.

  For getting the beast to boot, I attempted the following. The kernel should be installed, first, and the installation inspects the /proc directory, so this is prepared for it, too.

- Now the system should be installed. It was not clear from the documentation ([[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548424|#548424]]) about how the configuration file should be named - so some good soul please improve the description given here.
