We differ in our opinions there, I think.

Very much so.

I think that we can all agree on that. I'm just pointing out that the r*
commands are not going to go away and that some of us will continue to
need to maintain them in some fashion for at least the time being.
Regardless of the merits of yours or my arguments, we're not going to
switch to OpenSSH as our primary access method in the next year or even
the next two.

I'm not really interested in hearing arguments about how we should change
our infrastructure at this time. I understand the issues and I'll make up
my own mind on that point.

This, on the other hand, is worth at least examining, although it sticks
in my mind that we've tried this before and it didn't work. But I don't
remember the exact details on why it didn't work.
