Not sure what you mean with "once the distribution changes" but within a 
major CentOS/RHEL version (e.g. 5 or 6) there is a stable ABI so an 
update to the distro should not introduce issues. In my experience apps 
deployed on RHEL 5.1 work equally on 5.7. If they work crappy, hire 
better developers :)

So do people in the Windows world decide to *not* build msi packages 
because their PHB might decide to replace all Windows with RHEL/CentOS? 
I have never seen that (the not building msi packages that is). And 
neither the reverse. I build versioned packages so (amongst other 
things) I can create a controlled and predictable environment. Are you 
going to install from source on thousands of servers or do you push 
*one* tested rpm? I know what I will be doing. Anything else just does 
not make sense to me.
