Be careful here.  There are some subtle, but important differences.

With a script image, you are basically running standard commands,
which includes certain tests and limitations.  With "env import", you
are just importing a set of environment settings, without further
tests for permissions, etc.

For example, think if data like your MAC address or board serial
number are important to you, or if you are willing to have any user
overwrite these with arbitrary data.


Best regards,

Wolfgang Denk
