New World host filesystem handling

Path	Handled by
/etc	Jointly managed by apt which mostly provides default versions of configuration files, and cfengine which installs CSE-specific versions of configuration files
/usr/local/extrafiles /usr/local/extrapackages /usr/local/debpkgs_lists /usr/local/vmimages	cfengine
/proc /sys /dev	The kernel
/tmp /var	Whatever processes are running on the host
/export	The kernel's nfsd (i.e., NFS server)
/import /home	The automounter
Everything else	apt
