syspatch helps provide binary patches to OpenBSD. Simply run:

<code>
$ doas syspatch
</code>

This process can be automated by setting up a cronjob:
<code>
$ doas crontab -e
</code>

<code>
0      *      *       *       *       sleep $((RANDOM % 43200)) && /usr/sbin/syspatch
</code>

Notice that a random sleep has been inserted to ensure that the update starts at a unique time. This is designed to prevent all machines from running the exact same job at the exact same time, which would cause performance issues.
