Do you think the guest OS installer set some efi variable during the installation process, which bhyve did not save?

I was under the impression that efivars are stored in a configuration file in the EFI partition but I was probably wrong, they are kept in NVRAM somewhere, like BIOS settings, and not on a disk. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/
