Kadischi - more changes

[J. Hartline]

Hi.
There was some discussion in the mail threads yesterday
that we go ahead and do away with copying /root files with rsync in 
Kadischi.

I looked at it briefly and what I think can be done is not empty /root 
during 05fsclean.py
thus being able to drop the rsync'ing code out of it also in 
post_install_scripts.

The RAMfs will contain the files from /root in any case because they are 
bound from /livecd/tmpfs to /root.
Along with this change, I am curious if we should also "bury" the 
non-common directories
such as /livecd /initrd and /rr_moved e.g. make these hidden rather than 
having what would be
a very obtuse looking root dir.. simply moving these to /.initrd 
/.livecd and /.rr_moved for instance.
