The idea is to merge directory trees. Assume you have /usr in a separate file system and keep non-essential binaries in /usr/bin. You could then make /bin a shadowfs which merges the original /bin and /usr/bin, so that all executable programs appear in /bin even though most of them really are in /usr/bin. PATH=/bin would then be enough. IIRC, this has been implemented in some other operating system as "unionfs".
