The simplest solution is to set the subject DN explicitly on the command-line:

   $ umask 077 # avoid world-readable private keys
   $ openssl req -new -newkey rsa:2048 -nodes -keyout private/$your_host_tld.key \
	-x509 -subj "/CN=$(uname -n)" -out certs/$your_host_tld.crt \
	-days 3650 -extensions v3_req
