So I just tested the CD and it works perfectly. It boots, automatically configure the interface and launches the SSH daemon. For me this is the perfect tool to perform remote installations/fixing of FreeBSD. I just send the compressed 100 MB ISO image to someone, have him to boot the machine using the CD and then I log on the machine with SSH and do whatever I want. The only thing I had to do in addition to what I mentioned in my previous emails is to create a script in rc.d that runs just after root and that does the following: mount /etc_tmp #Mount memory disk to /etc_tmp cd /etc_tmp && tar -cp -C /etc -f - ./ | tar -xpf - #Copy content of /etc to /etc_tmp mount /etc #nullfs mount /etc_tmp over /etc Obviously I have also changed the root password and created a user that is a member of the wheel group.
