Yes, those scripts will run "ip rule" to process the contents of the 
"rule-*" files.  The company I work for uses shorewall on all of their 
multi-homed systems, so I'm not sure how systems without it behave. 
That said, I don't see any magic in the init scripts to handle this 
without your input.  I'm inclined to believe that something on your 
system was manually configured to set up the routing policy that you see.

Find it harder:
find /etc/ -type f -print0 | xargs -0 grep "ip rule"
