Installing Ubuntu with no internet access

[Gerhardus Geldenhuis]

Hi Piere,
Thanks for the response. I did see the ntp section after posting it and
setting it to something local made a small difference.

My solution in the end was to add:
# This line will contact archive.<domain>/ubuntu
d-i apt-setup/security_host string archive/ubuntu

This caused the installer not to reach out to the internet and use the
address that I specified resulting in a significantly faster install.

Regards
