they use a trick close to mine (i just save some disk space using a tarball

8.) To make postgres work off the CD you need to pull a little trick here:
        copy /var/lib/postgresql to /etc/skel/postgresql

i have been said that one of the interesting fields to investigate would be 
the use of shmfs-Ramdisk and/or LVM
apparently that would enable me to store only the differences in the ramdisk

has any of you already tried that ?
