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).
