And how can we do that?  I don't know of a way that would be reliable
and less confusing than the current situation - every Linux distro
ships a different kernel and version of CUPS, and we don't have the
resources to keep up with them or detect which variant you happen to
be using.

I can't comment on whether ESR is an "authority" - I've never met
him in person, and my only exposure to him has been through his
articles/rants.

However, you are correct that ESR had problems with his Linux
distro of choice back then, just as you are having problems now.
I can only say that you will likely get better support if you
contact your Linux distributor, as they make extensive changes to
CUPS and the Linux kernel.  Since each one makes different changes,
we have to rely on the distro to support their stuff...
