$ man mount
# look at the --bind and --move options.
At the moment, I'm not sure about the distinction between them, but I
use --bind in a few places. Like binding /var/tmp and /usr/tmp,
/usr/local and /home/local, and /dev/shm and /tmp. The last of these
gives you /tmp in memory, which is faster and automatically cleared on
reboot, for bettor or worse.
