well, I have no idea what vserver version is in that kernel,
but let's hope the debian folks made a good choice ...

that is part of the resolve mechanisms of libc
(read: you have to consult the config e.g. /etc/nsswitch.conf
and talk to the debian folks, if it doesn't do what it's
supposed to do)

basically you could setup a dhcp (on the host) and
send out requests with some identifier (guest) to
reiceive answers and then parse them and write them
into the file ... OTOH you could simply remove one
of them from the guest :)
