then debian butchered the SVR4 file system layout. whole idea
of having /boot and /var was to make sure that diskless systems
that nfs-ed everything else could count on having local storage
in /var and a minimal amount of anything required in /boot.
just about everything else on the planet assumes that /var/tmp
is a replacement for /tmp and should 01777...
