Tree 4.3.1
An exception is made for the X Window System because of considerable precedent and widely-accepted practice.
The following symbolic links to directories may be present. This possibility is based on the need to preserve compatibility with older systems until all implementations can be assumed to use the /var hierarchy.
/usr/spool -> /var/spool /usr/tmp -> /var/tmp /usr/spool/locks -> /var/lock
Once a system no longer requires any one of the above symbolic links, the link may be removed, if desired.
