I tested this patch and the report contains:

``````
$ `ls -l /dev/disk/by-*`
```

```
STDERR:
```
ls: cannot access '/dev/disk/by-*': No such file or directory

```
``````

perhaps we cannot use a glob pattern in this environment? Note that the
command runs just fine with bash (over ssh) on the machine where this
was tested.

Other than that, this would be an excellent addition.
