sample-configurator: Sample-edit added

Starting to have second thought about do this scriptin. At least in
dialog. It's far to cumbersome. Some kind of XML-editor would do
the same just as good. Or even forms/database cambo...

Evaluating sysfs

Files in sysfs doesn't behave like any files I've encountered so far,
device-driver files or normal files alike. They are just strange.

Observations so far:

* They don't block (ever?)
* The do send out EOF, but tar -f still won't re-read them
* Time-stamps don't change, except when first read. It's my belief it's
  when such a file gets accesed the first time, the inode for it is created.

ls --time=<type> --full-time <file>

..will show the same time as when first accessed (including the operation
above) and it will remain that way, regardless of <type>. Not shure if
inode info will give any more information.

I.e. my conclusion is that reading a sysfs is a direct callback to the
driver owning the file and that any data is created (i.e. provided) there
and then on demand.

When it comes to files under /dev, they seem to share the same properties
regarding at least time, i.e. times in stat are not updated since creation.
