Yes, I did that before I posted my original message. (I also just redid
it, to be sure that I didn't miss something the first time.) There is
no variable in the perl code with that name. There is something in a C
program (dbdimp.c), but it's not clear where it's getting the value,
or how I'd go about resetting it.

Nope, nothing there.

I did narrow it down, though (I think) to
/usr/local/rt3/lib/RT/Handle.pm, which is the RT module that sets up
the connection to mysql. There's nothing in there that specifies the
socket name, though, so I guess that hasn't been added to RT.

That's just from the man page - not real perl code. :-(

Still, all this shouldn't really be necessary. If RT (or Perl DBD)
would respect /etc/my.cnf, life would be easy.
