For some reason /dev failed to mount. Normally, the kernel 
automatically mounts / read-only and /dev read-write. The former is 
upgraded to read-write by the rc scripts during multiuser boot.

It could be a bug in 11.3.

The menus are somewhat improved in stable/12 and head. Here are some 
screenshots from a VM I just booted, it runs head from February(!):

That dark blue colour is my only complaint. It can be a real pain to 
read on certain terminals/video adapters.
