I don't mean to discourage you, but every additional complexity comes at risk and it case of GELI this is security risk. What is missing in your work is explanation how it that useful for the users? How do you use it? First I need to understand and be convinced that this functionality is generally useful and thus is worth additional complexity and risk.


I can't speak for Mr Romero, but I imagine what he's after is plausible deniability. The GELI metadata on a volume unambiguously declares it to be encrypted data.

Properly implemented, I think this could be a worthwhile enhancement for certain applications or circumstances where one may not wish to invite further scrutiny.
