I think it's this:
I don't know much about the internals of GBDE, but if we take his
description of it at face value, it seems to be fair criticism.
I think it's actually saying that GBDE assumes the user will provide
enough user-key entropy, and doesn't do anything to mitigate the use
of weaker passphrases.
Geli uses salt and PKCS #5 so it's pretty much blameless in this area.
