what it does is replace "@uid" and "@uid/" with the real uid of the
process. so:

  /tmp -> /real_tmp/@uid

for example would translate /tmp to a different path depending on
who accesses it. (not implying any use, that's just a keyword for now
that I thin is useful for that and possibly other purposes)

maybe if the magic symlinks had a man-page, or entries on sysctl
man-pages, you would have easier time understanding what this does.
