There seems to be a difference. When I used 'allow-hotplug eth0', pump
was no longer running. I've done the same test with 'auto eth0' (i.e.
boot with the network cable unplugged, then plugged it in again), and
'pump -i eth0' was still running... but after 5 minutes, the interface
was still down. 'pump -i eth0 --status' was saying 'Operation failed.'
(at boot time, this was normal since the cable was unplugged, but this
doesn't explain why it was still saying that more than 5 minutes after
plugging in the cable). Running 'pump -i eth0' brought the interface
up.
So,
1. 'allow-hotplug ath0' doesn't seem to work (either it doesn't start
pump or it kills it), but I doubt that pump is the cause since it
is still running if I use 'auto eth0'.
2. There's a bug in pump, as it doesn't seem to try again if DHCP is
available.
