http://bugs.debian.org/669666

Dear Maintainer,

Can you please forward upstream about this non interactive mode
I did workaround this , using a hacked "expect script"
I can share it (*), but I am fully happy with it...

So I'd like to put a resume task in my init script..

Recovering large disks could takes more than month ...

==== EXT2/EXT3/EXT4 ====


I prefered to use ext4magic as : 

    sudo ext4magic  /dev/sdc3 -r -f $USERl/Documents/ -d /tmp/local/tmp/


Note you have to resolv symlink by your own
