That seems like a really odd thing to do.  Why not translate zone.tab?
That's what user interfaces should be using to select zones anyway.
The TZid is just a token you can hand to the C library (the fact that
it's also a pathname is just an implementation detail).

In recent releases of FreeBSD the tzsetup utility automatically stores
the installed zone's TZid in /var/cache/zoneinfo so that it can be
reinstalled without user intervention when the tzdata is updated using
"tzsetup -r".  Many FreeBSD machines still have a separate /usr
partition becuase that is the traditional partitioning setup.
