357: The MacOS installer shipped with OpenBSD 2.7 does not correctly make all
358: devices, specifically it does not make the <code>/dev/arandom</code> device
359: needed for the userland crypto such as ssh to work. The problem shows itself
360: when ssh-keygen fails to make RSA or DSA keys, resulting in messages like
361: <b>RSA-generate_keys failed</b> or <b>DSA-generate_keys failed</b>.
362: <br>
363: To work around this, once your machine is up and running run the following
364: commands as root:
365: <pre>
366: # cd /dev
367: # ./MAKEDEV arandom
