I am not aware that the hostname of the system must resolve into
something usable.  I am only aware that sudo prints an error 
message (which may be harmless) if the hostname isn't resolvable
at all.

I am not sure that that is necessary.  It seems that one can connect
to 127.0.1.1 without further ado.  I have dnsmasq running, for example,
and it answers queries made to 127.0.1.1.

$ host www.matrox.com 127.0.1.1
Using domain server:
Name: 127.0.1.1
Address: 127.0.1.1#53
Aliases:

www.matrox.com has address 138.11.241.200

I wouldn't expect this to work given my routing table:

$ sudo route
Kernel IP routing table
Destination  Gateway    Genmask         Flags Metric Ref    Use Iface
192.168.0.0  *          255.255.255.0   U     0      0        0 wlanp_0
default      hubert     0.0.0.0         UG    0      0        0 wlanp_0

But it does.

Yes, better wait until the debian-devel discussion is finished.
