No, that's not it. Both systems are known on my DNS server. It could still
well be a DNS issue, but nothing that easy.

I've reproduced it just now during an installation using the sparc64 RC3
netinst CD. The pause during power off is at the "start-stop-daemon
--stop" command.
The pause is about the same as when exim is being restarted during
reconfiguration in the first situation.

During previous installations with "local mail only", the default for the
hostname would mostly be the system name. Now I see
"localhost.localdomain" in some (all?) installations. Could that be the
root cause for both these issues?

This could be something from the d-i installation.
On this new Sparc installation I get in /etc/hosts (DHCP with fixed
address):
127.0.0.1 localhost.localdomain localhost gimli

On another installation I have:
127.0.0.1 localhost.localdomain localhost
10.19.66.2 elrond.fjphome.nl elrond

So on the new install the FQN is missing in /etc/hosts, but it is also
readily supplied by my DNS server:
fjp@gimli:~$ ping gimli.fjphome.nl
PING gimli.fjphome.nl (10.19.66.9) 56(84) bytes of data.
64 bytes from gimli.fjphome.nl (10.19.66.9): icmp_seq=1 ttl=64 time=0.273
ms
64 bytes from gimli.fjphome.nl (10.19.66.9): icmp_seq=2 ttl=64 time=0.083
ms

Would you like me to file a separate BR for this or will you clone this
one?

Cheers,
FJP
