Make symbolic links relative?

This is a NFSv2-specific option.
Converts absolute symbolic links seen by the client to relative links.
For example, if the directory /usr was exported, a link from /usr/local/bin to /usr/X11R6/bin would be converted to ../X11R6/bin. This makes a lot more sense if the client is mounting the directory somewhere else than /usr.

exportfs option: link_relative
