I&#x27;ve modified configuration files on a FreeBSD filesystem image with a hex editor to cause it to obtain a dhcp lease and allow password ssh login for the default account. (Linux cannot read&#x2F;write to the default FreeBSD filesystem.)<p>This allowed me to set up the RPi headless and keyboardless.<p>Of course the filesystem was dirty, but it&#x27;s nothing an fsck couldn&#x27;t solve.
