Yes, indeed.  Core files are truncated to zero bytes by default on _any_
system run by a self-respectingly paranoid sysadmin -- which serves
nicely to get to my point:  I get really tired of alleged security
discussions that presuppose incompetent administration.

Competent sysadmins don't use wu-ftpd.  Competent sysadmins don't drape
security-sensitive corefiles around their systems.  Competent sysadmins
monitor relevant security-alert sources, and act on them immediately.
Competent sysadmins aren't shocked to find out that shadowing and NIS
don't mix.  (Competent sysadmins also go to some lengths to avoid
NIS/NIS+, when possible.)  

Competent sysadmins don't cite dumb-sysadmin errors, bad practices, or
known-but-unpatched security bugs as somehow indicating a systematic
problem with (e.g.) password shadowing.

Yet, you two goofballs have been doing little else for the past few
days.  That's a bit of a waste of everyone's time, isn't it?
