BSD Certification Group... it was Jim Brown who has done these.

Jim is on list (I think)... so he can reply, but I think the build
script is out there.  It's QEMU based IIRC.

Can you clarify?

So you want all the BSDs to boot off usb, and then to have a writeable
slice for dumping the dmesg?

And dmesgd is a great destination for those dmesgs!

I can now see hundreds of BSD people around the globe wandering big-box
computer stores booting off USB sticks before security arrives...
