Option 5, this is normal CD-operation I think? (not shure, I use a special harddisk-install, so have no such menu).Now a question, i booted with option 5, first boot, hod do i to save the configs, net, xorg, ...? =)
Usually, when you shutdown, you will be offered to save your settings in a file called pup_save.3fs.
This uses 512 MB (if available, else less), and includes its own internal ext3-filesystem.
On next boot, it is mounted automatically, and merged with the read-only folders of pup_201.sfs from the CD, that includes the base-system like X.
This is achieved using "unionfs", so it is possible to write to /usr/X11R6 for example, though originally it is write-protected (as it is on the CD).
