Bug#806386: pbuilder: No more updates /etc/resolv.conf inside the chroot, hence no more DNS inside chroot after network change

Yes.

That will not be enough (network is much more than just DNS).

On the other hand, DNS must be done with care, to not break
peoples’ testsuites. That means, resolv.conf may be empty,
the Solaris/GNU nsswitch must use files, may skip dns, but
/etc/hosts in the chroot probably needs two lines:

127.0.0.1 localhost $(hostname -f) $(hostname -s)
::1 localhost $(hostname -f) $(hostname -s)

Unfortunately, the intrinsics of several of the Solaris/GNU
things we don’t use in the BSD world (nsswitch, PAM, etc.)
are beyond the set of skills I’m good at, so I cannot give
definite advice. Best to ask others in addition.
