[Pbuilder-maint] Bug#391915: pbuilder: pbuilder-uml should not overwrite network configuration

[Marcus Better]

Package: pbuilder
Version: 0.159
Severity: normal
Tags: patch

pbuilder copies the system's /etc/{resolv.conf,hosts,hostname} to the
build chroot. This is wrong for pbuilder-user-mode-linux, since the
host information is not necessary correct for the guest.

For example if the host has "nameserver 0.0.0.0" in /etc/resolv.conf,
then the UML guest will have a broken network configuration.

The following patch appears to fix it.
