I have thought about building both MySQL packages as a separate daemons but 
the problem is that since they are one and the same, they use the same port 
,the same configuration files and the same data directories. 

Althou that could be changed with a few simple patches this would make them 
somewhat cripled. 
Also the userland tools use the same configuration files (~/.my.cnf) which will 
complicate things even more.

Is it possible for the EPEL policy to bend a little here for at least one of 
these packages ?


Best regards,
