Not sure if this is the correct place.... (laptop, dual-boot EFI)

[Karl Denninger]

Further question....  does boot1.efi (which I assume has to be placed on
the EFI partition and then something like rEFInd can select it) know how
to handle a geli-encrypted primary partition (e.g. for root/boot so I
don't need an unencrypted /boot partition), and if so how do I tell it
that's the case and to prompt for the password?

(If not I know how to set up for geli-encryption using a non-encrypted
/boot partition, but my understanding is that for 12 the loader was
taught how to handle geli internally and thus you can now install 12 --
at least for ZFS -- with encryption on root.  However, that wipes the
disk if you try to select it in the installer, so that's no good -- and
besides, on a laptop zfs is overkill.)

Thanks!
