5.2.1-RELEASE and install.cfg unable to find ad0s1b dev node

[Ivan Fetch]

Hello,

    I've searched the mailing lists and found others with this issue, but 
haven't found a solution yet - can someone point me in the right direction 
please?

    When using an install.cfg file with 5.2.1-RELEASE, I get:
             Unable to find device node for /dev/ad0s1b in /dev!
             The creation of filesystems will be aborted.

    Even if I set the DiskInteractive variable before running the DiskLabel 
editor, the above error still appears.


    Here is my install.cfg file:
installVarDefaults

debug=yes
# Networking Options

domainname=domain.com
nameserver=192.168.0.254
defaultrouter=192.168.0.254

# Even commenting out the above and uncomminting the below, install still 
fails.

    Thanks in advance for your help,
