This is done using mfsBSD, which can be booted from pxelinux and contains a script to automatically install FreeBSD using ZFS on root. After the install the host is set to boot from the local disk. Signed-off-by: Roger Pau Monnà <roger.pau@xxxxxxxxxx> Cc: Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx> --- Changes since RFC: - Set the bridge to use the MAC from the first added interface instead of generating a random one. - Launch DHCP on the bridge instead of the nic. - Add a list of FreeBSD ftp mirrors and iterate over them in order to find a working one. - Add support for finding the primary disk and nic automatically. - Switch shell to sh (instead of the default csh), and use set -e in order to exit if a command fails. - Replace echo "-Dh" with printf "%s" "-Dh". - Copy installer keys into the installed system in order to prevent it from generating new keys on the first boot. --- ts-freebsd-host-install | 235 +++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 235 insertions(+), 0 deletions(-) create mode 100755 ts-freebsd-host-install diff --git a/ts-freebsd-host-install b/ts-freebsd-host-install new file mode 100755 index 0000000..06caeaa --- /dev/null +++ b/ts-freebsd-host-install @@ -0,0 +1,235 @@ +#!/usr/bin/perl -w +# This is part of "osstest", an automated testing framework for Xen. +# Copyright (C) 2009-2014 Citrix Inc. +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU Affero General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
