I use this myself! It's been handy, but some SRPM authors, especially
3rdparty ones, have used some very strange logic based on %dist.. I
try to straighten it out, but it can be hard with low maintenance
projects.

If you want *weird* logic, go look in the Samba SRPM's from
http://ftp.sernet.de/pub/samba/3.6/src/rpm/samba3-3.6.0-44.src.rpm.
That scan's /etc/*-release files.....
