      Dear Javier Martinez Canillas,

Based on commit cf073e49bc3502be1b48a0e3faf0cde9edbb89db for beagleboard
Using the new env import command it is possible to use plain text files instead
of script-images. Plain text files are much easier to handle.
Are you sure you want to do this in a production environment? The
ease of use may be helpful during development, but please note that
there is no validation of the content passed to env import in any way
- and feeding it crap you can even crash the system - not to mention
from the problems that can result from corrupted environment settings.
Script images are checksum protected, which appears to be a
significant advantage to me - also, they carry information like name
and timestamp, which in production environments are often very helpful
to diagnose problems (like asking your customers: which exact version
of the environment script are you loading?).
Best regards,
Wolfgang Denk
