realpath(3) does work.

I have used this little wrapper:


And after compiling and running it, I do get the real path:

# ./test_realpath /usr/local/rrd/stable-crm2/repository/manager.nbg/ 

However calling "rrd_graph" to read "/usr/local/rrd/stable-crm2/ 
repository/manager.nbg/switches/whk2s1/10146.rrd" does not cause it to  
flush to disk.
