My config looks like:

    error_log  syslog:server=unix:/dev/log;

The only error I see is that nginx can't open /var/log/nginx/error.log.

    $ nginx -t
    nginx: [alert] could not open error log file: open()
"/var/log/nginx/error.log" failed (2: Unknown error)
    nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    nginx: configuration file /etc/nginx/nginx.conf test failed

Of course /var/log/nginx isn't there because I'm trying to use syslog.
If I create /var/log/nginx, nginx starts and I'll see debugging logs
there but nothing related to syslog problems.

The permissions on /dev/log look fine:

    $ ls -l /dev/log
    srw-rw-rw-    1 root     root             0 Jun 24 12:41 /dev/log=
