I want to decrypt to raw or mount one aes encrypted overlay partition created with Knoppix 7.6.0. Password is known.
The partition has a broken file system (reiserfs), so normal boot halt with a fail message from UNIONFS.
I want to mount it after I start with noimage option or on another installation and try to fix it. The partition was damaged after copied a large file who exceeded capacity.

Any idea are welcome. Thank you.
