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