Ok, I just tried mkgroup -lcd, but that included many lines of
irrelevant cruft from the corporate domain.  So I just removed the
mkgroup_l_d line from /etc/group; is that what you recommend?

That, alas, did not fix the problem.  Running cron-config still
produced the following when it tried to start cron as a service:

Beats me; possibly.  In any case, all of its settings are locked down
and not changeable by me.  Is this specifically known to be a problem?

Still, I'd think it would log _something_.  But that's just my guess,
and unlogged weird interactions are of course both possible and common.

Good point.  There's a software firewall, also not modifiable by me,
called Proventia Desktop.  It's been logging an interesting number of
UDP probes, but nothing cron related.  One more bit of evidence: I can
(temporarily) turn it off, and doing so does not fix my cron problem.

It is very dark & after 2000.  If you continue, you are likely to be eaten by a bleen.
