This is not true for zLinux (Linux on an IBM mainframe).  Disk space on 
a mainframe is quite expensive compared to what we are used to on Intel
hardware.  I have customers who use a shared /usr among several zLinux
systems, and the reason is cost savings.  

I don't blame anybody on this list for not knowing about this, but I 
find it amazing that Red Hat doesn't know better.  They are a major
supplier of Linux for mainframes.  (FYI, that's the s390 and s390x 
architecture that you see available from a handful of distros).
