The policy rules for symlinks are distinct from those for regular files, 
directories etc. So when the usual, expected filesystem layout for an 
application and its data doesn't use a symlink, there's unlikely to be 
selinux policy for following syminks for that application.

The admin's old trick of shuffling data around and putting a symlink to 
the new location from the old location probably needs to be accompanied 
in most cases by local policy modifications to establish the contexts 
for files in the new locations, and to allow the symlink to be followed.
