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