bareboxenv-target not loading correctly

bareboxenv-target not loading correctly

[Boulais, Marc-Andre]

Hi,
I am trying to modify the Barebox (v2015.02.0) environment from the application. To do so, I execute the following commands from Linux:

root@SBC-172:/root mkdir -p env
root@SBC-172:/root bareboxenv-target -v -l ./env /dev/mtdblock2
loading env from file /dev/mtdblock2 to ./env
root@SBC-172:/root ls -al
drwx------    2 root     root          4096 Jan  1 03:29 .
drwxr-xr-x   19 root     root          4096 Jan  2  2000 ..

bareboxenv-target seems to succeed in loading env but the "env" directory has disappeared...

Any thoughts or suggestion would be greatly appreciated.
Thank you,

The directory shouldn't be removed, that is a bug. I just sent
a patch.
Anyway, the directory will stay empty even after applying the patch.
That is a side effect of only storing the differences to the default
environment. Once you have made changes they will show up there.

Great, It works. Like you said, the directory is no longer empty once I modify the environment. 

Thanks
