-			 * The Unix conformance test suite expects the
-			 * console to be a socket or a device node on a
-			 * normal writeable file system.  It tests console
-			 * functionality such as fmtmsg(MM_CONSOLE) by
-			 * temporarily replacing that socket or device
-			 * with a regular file which it can then inspect
-			 * after the test.  This worked fine in the 1980s,
-			 * but we are no longer in the 1980s, so in order
-			 * for the test suite to work at all we have to
-			 * lie and tell it that the console is
-			 * `/var/log/console`.
-			 *
-			 * Furthermore, part of the test suite for
-			 * fmtmsg() attempts to verify that it returns the
-			 * correct error codes when it fails to write to
-			 * the console (either MM_NOCON if it successfully
-			 * wrote to stderr or MM_NOTOK if it didn't).  It
-			 * does this by replacing what it thinks is the
-			 * console with a directory, rather than a regular
-			 * file, in order to trigger a failure from
-			 * fopen().
-			 *
-			 * In order to pass this misbegotten test, we
-			 * check to see if `/var/log/console` exists and
-			 * is a directory.  If that is the case, we try to
-			 * open that instead of the real console.  We will
-			 * of course fail, but that's what we're expected
-			 * to do at this point.
