# cat /proc/mounts | grep var
/dev/VolGroup00/LogVol02 /var ext3 rw,data=ordered 0 0

I can't unmount var.
I think it is like Ross already wrote, that /var can't be unmounted in 
multi-user mode.
It would be nice if someone could explain why /var is unmountable, even 
when "fuser -mv /var" and "/lsof /var" doesn't return any files.
