Configuration of first interface
When installing FreeBSD 10.1 using the default bsdinstall, configuration of a second network interface is overwritten or fails to write to /etc/rc.conf.
I am using a VirtualBox VM with two virtio network interfaces. Both are detected properly and both are listed on the first stage of network configuration. Even though I configure each interface using bsdinstall's interface, only the second interface's config is written to /etc/rc.conf.
It seems that the config for the second interface is the only one that gets written to /etc/rc.conf
I have attached a video clip of the install process and at the end I cat /etc/rc.conf to demonstrate that there's only one configuration that was written to /etc/rc.conf

cat /etc/rc.conf to show missing config for first interface
No video. Just screen shots.
I am also running into this issue with FreeBSD 11.0 STABLE.
Got bitten by this on 12.1 as well.
