Subject: [PATCH] Test/stages: check dracut stage output for environment
 warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extend the dracut stage test case with checks for error / warning
messages complaining about unsupported / incorrect runtime environment.

Messages such as:
```
/dev/fd/63: No such file or directory
```
or
```
/proc/ is not mounted. This is not a supported mode of operation.
Please fix your invocation environment to mount /proc/ and /sys/
properly. Proceeding anyway. Your mileage may vary.
```

The stage will be fixed in the next commit.
