Yup, this is a bug .. in something.

What is happening is that the Ubuntu libpam-systemd package has a
post-install script that tries to communicate with the init system
(which it expects to be running, but isn't running inside the
libguestfs appliance).

The obvious way to fix this would be to use a firstboot script instead
(assuming that is working - didn't you say you had a problem with
that?).  Something like:

  $ virt-builder ... --firstboot-command 'apt-get -y update ; apt-get -y upgrade'

It may be there is some other method based on persuading the systemd
post script not to run, or not to try talking to the init process ...

Note that --update is just a convenient shorthand for:

  --run-command '
     export DEBIAN_FRONTEND=noninteractive
     apt_opts="-q -y -o Dpkg::Options::=--force-confnew"
     apt-get $apt_opts update
     apt-get $apt_opts upgrade
   '

You can play around with that command until you get something that
works better.
