Path to the directory containing the custom barebox

environment. Depending on your setup, it will probably be
|
||||
based on either the content of the defaultenv or
|

defaultenv-2 directories in the barebox source code, plus
|
||||
the additions needed. The output will be an image in the
|

barebox devfs format, stored in the images directory, with

the same name as the directory name given here.
