Overview: Flying is a X-Windows program I have found installed on Redhat   
5.2 that is actually a gateway for multiple games that Helmut wrote. All of  
these games unfortunatly write to /tmp/logfile.txt . Basicly all that you  
have to do is symlink logfile.txt to say /var/log/messages, and as soon as  
root runs his silly little game it overwrites logfile.txt with the file you  
symlinked it to, also it becomes owned by root and the symlink is turned  
off. The big but is that the read bit is left on allowing you to read the  
tmp file. Do I have anything better to do than find stupid tmp file holes  
in mostly unused games? No not really.
