Re: UEFI booting survey [and compared ubldr.bin booting behavior]

[Just adding notes about what ubldr.bin does with and without loaderdev being specified (correctly). Overall it does not appear to me that the ubldr.bin based contexts can fully avoid the "systems with multiple partitions that might be right" issue.] On 2017-Dec-20, at 2:47 AM, Mark Millard

Greetings If you are booting off UEFI and have a bit of an unusual setup, I'd like you to drop me a line. The setup that I'm looking for is any case where you load boot1.efi off one drive (cd, ssd, hdd, nvme, etc), but don't have a FreeBSD system on that drive, but on a different drive on the
