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