OK, I confirm that this is a problem with pump (its man page sucks and
I didn't know how it should have behaved) on this particular machine.
But then, I don't see why I should use 'allow-hotplug eth0' instead of
'auto eth0'.

On my laptop, when I type "pump -i eth0" (the device exists but is
down and not connected), I get the error message "Operation failed."
(as expected), but "pump -i eth0" is still shown by ps. So, this
confirms what you are saying.
But on the other machine (on which I have the problem I mentioned at
the beginning of this thread), when I type "pump -i eth1" (again, the
device exists but is down and not connected), I also get the error
message "Operation failed." as expected, but "pump -i eth1" is no
longer running. I think this can explain my problem if it can be
confirmed on eth0 too (I'll have to try that).
Note: I do not have a /etc/pump.conf file on any machine.

I just have:
Jul 3 14:11:22 vin pumpd[2478]: PUMP: sending discover
And on June 28/29, /var/log/syslog doesn't show anything about pumpd
at the time the Ethernet cable was disconnected.

In particular, this was a discussion in debian-user-french in June 2004,
so with Debian users.
