You don't have to do it like this. You can use mkzftree during the last stages 
to create compressed file system that the kernel knows how to read. Reading 
from the squashfs page, they use gzip so isn't it the same? I looked at cloop 
and decided there was no gain from mkzftree.

This is more or less normal for livecds.

Right. This is an improvement in terms of memory space. I also include /etc in 
tmpfs because networking stuff wants to write there.
