I read that bug report VERY carefully. Twice. There is *nothing* there that
seems to have been fixed/addressed by .localdomain, except maybe a DNS
timeout in Pierre's machine. Everything else deals with the hostname.
Or am I getting confused and d-i uses localhost.localdomain as the default
hostname, and say, if I had told it that my machine is named "twerk", domain
"foo.bar" I would get a
127.0.0.1 twerk.foo.bar twerk localhost
entry in /etc/hosts?
That would explain a lot... but still make such a "fix" quite a bad idea.

This could cause trouble that is easily avoided by actually adding an extra
loopback address to lo (or a lo:1 alias if you have to use ifconfig) of
127.0.1.1. This is harmless and could be added statically and
unconditionally to /etc/network/interfaces.
