On Yellow Dog Linux, a PPC distribution that has nothing to do with 
RedHat except it's modeled after it:

linux% cat /etc/redhat-release
Yellow Dog Linux (CS-1.1)

linux% rpm -qf /etc/redhat-release
yellowdog-release-CS_1.1-1

So don't go making too many assumptions just because 
/etc/redhat-release exists.  In this case, it's a symbolic link to 
/etc/yellowdog-release.
