The question then becomes whether multiple efi loaders can be told to each use a *different* partition to load the kernel from (and thus the loader file, which in turn can tell it where the root filesystem is.) Reading through the man page it appears they may not be. You could of course interrupt it and manually select that, but I suspect that's not what you want to have to do. I use refind on a dual-boot (win10/FreeBSD) system but not with multiple independent FreeBSD versions.
Thanks for all the detail, Karl. I was also looking at those details. It occurs to me that an *ideal* arrangement might be the ability to name each efi loader according to it's target, or probably better; (name) the directories that hold the loaders. It just seems wasteful/inefficient to create x number of efi partitions for x number of OSs. Maybe boot0 could be coerced info something similar? I'm currently looking at Clover (popular with the "hackintosh" users) that seems to do something similar. Thanks again! --Chris
