Using FreeBSD's Bootonly Installer Behind a Proxy
I’ve been so busy for the last month that I almost forgot about FreeBSD 12.0 which I had been looking forward to. Now it’s just around the corner!
Although it’s quite late, I tried to install 12.0-RC3 on a host behind a HTTP proxy and found that using a bootonly installer in this environment was a bit tricky. The following are the steps I took.
Boot the host with a bootonly installer.
Go into Shell at the Welcome dialog.
Select an appropriate keymap for my keyboard.
kbdcontrol -l jp
Set the http_proxy environment variable to let installer fetch distribution sets (tarballs) via proxy.
Run the standard installer program ‘bsdinstall’ and proceed to disk partitioning screen.
Just before hitting OK at the “Last chance!” confirmation dialog, press [Alt] + [F4] to open a console and set up IP and DNS configurations. If a DHCP server is available, the easiest way is to run the following command.
If not, manually configure IP address with ifconfig and add nameserver lines to /tmp/bsdinstall_etc/resolv.conf (symlinked to /etc/resolv.conf). It’s might be something like:
ifconfig em0 inet 10.0.2.15/24 route add default 10.0.2.2 echo nameserver 192.168.10.1 > /tmp/bsdinstall_etc/resolv.conf
Go back to the installer screen with [Alt] + [F1] and go on.
Before exiting the installer, I usually ran the following commands in chrooted shell to rearrange ZFS dataset to use true /home instead of /usr/home symlinked to /home.
zfs rename zroot/usr/home zroot/home zfs set mountpoint=/home zroot/home rm /home
