Let's see, where to begin to respond...

1. This *is* the CentOS list, last time I looked. We don't use apt-get.
2. A fair bit of the system software on ubuntu is several releases newer;
     therefore, anything written on the current release of that will not
     run on an enterprise distro for years.
3. Ubuntu is, as far as I can tell, targeted at the desktop user. It is *not*
     targeted for servers.

Ubuntu has both desktop and server versions.  Further, it also has Long Term Support versions that are supported for 5 years and are broadly equivalent to CentOS Major versions.

When I was there Google ran its entire server fleet on Ubuntu.  I'd say that counts as enterprise servers.  If you count AMIs rather than actual instances, Ubuntu is far and away the most popular distro on Amazon Web Services:

4. Finally, yum has nothing to do with this: it's all repo software, not
      how I get it.

Now, I AM most certainly derogatory about the developers. *Most* large organizations, and larger libraries, are *not* going to be running The Latest Ubuntu, with Unity, or whatever; that *is* who, by default, they're targeting. Now, if the software was intended for home users (and I need to implement a library system for my own library), that would be fine. But it's a bad idea for the actual target audience.

Of those web sites running Linux, more than half run either Ubuntu or Debian (and CentOS barely edges out Ubuntu alone):

http://w3techs.com/technologies/details/os-linux/all/all

So a simple majority of the administrators of those sites would prefer .deb over .rpm packages.

In summary, point 2) above is mooted by the existence of LTS Ubuntu versions, and point 3) is just plain wrong, I'm afraid.  But I'll grant you points 1) and 4).  :) 

Tony.
