For what's worth we are using modded GBDE in one of the products to provide copy protection for the firmware and encryption of user's data. GELI is nice, but it's way much more end-user oriented. Also GBDE code is very stable, which may look bad from somebody using it to protect his pr0n collection, but from the PoV of us as ISV we have very little trouble porting our changes from FreeBSD 6 that we've started with originally to 7, 8, 9 and the FreeBSD 11 today. I would be really sorry to see it nuked from the FreeBSD without any good technical reason. Just my CAD0.02c. On Sat, Oct 24, 2015 at 8:58 AM, Julian H.
