'gptbootlite' would be what gptboot was until recently. I Agree with smh@ that we don't want to end up offering 10 different bootcode options. The installer, since 10.1 has created 512kb freebsd-boot partitions, specifically to allow the boot loader to grow in the future. > > P.S.: Allan, do you plan to enable GELI support for boot1.efi? Yes, I hope to have this done and present it at BSDCan.
