- * 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.
