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