Here is the code in question.

https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythbase/mythcoreutil.cpp#L39

It's not doing anything fancy, it just runs statfs on the path you give 
it.  If that path lies on some other filesystem, and you're tricking it 
with symlinks, it makes no attempt to outsmart you.
