"Size Limit -- Until OpenBSD 3.0 was patched to exceed it, the maximum usable encrypted virtual filesystem size was about 2.2 GB. Now, although I have not actually verified it myself, I understand that the maximum size is about 8.2 GB, this limit being due to a limitation of mkfs when working through a vnd mounted filesystem."
8.2GB I hope that a joke. I want at least 100GB.....
Besides of that I was hoping for full HD encryption.
