Absolutely certain.=C2=A0 The system board in this machine (and a bunch I=

have in the field) are SuperMicro X8DTL-IFs which do not support UEFI at
all (they have no available EFI-capable bios.)

They have encrypted root pools but due to the inability of gptzfsboot to
read them they have a small freebsd-zfs partition that, when upgraded, I
copy /boot/* to after the kernel upgrade is done but before they are
rebooted.=C2=A0 That partition is not mounted during normal operation; it=
's
only purpose is to load the kernel (and pre-boot .kos such as geli.)

Partition "2" is the one that should boot.

There is also a da2 that has an identical layout (mirrored; the drives
are 240Gb Intel 730 SSDs)

> What is the actual boot error?

It says it can't load the kernel and gives me a prompt.=C2=A0 "lsdev" sho=
ws
all the disks and all except the two (zfs mirror) that have the "bootme"
partition on them don't show up as zfs pools at all (they're
geli-encrypted, so that's not unexpected.)=C2=A0 I don't believe the load=
er
ever gets actually loaded.

An attempt to use "ls" from the bootloader to look inside that "bootme"
partition fails; gptzfsboot cannot get it open.

My belief was that I screwed up and wrote the old 11.1 gptzfsboot to the
freebsd-boot partition originally -- but that is clearly not the case.

Late last night I took my "rescue media" (which is a "make memstick"
from the build of -STABLE), booted that on my sandbox machine, stuck two
disks in there and made a base system -- which booted.=C2=A0 Thus whateve=
r is
going on here it is not as simple as it first appears as that system had
the spacemap_v2 flag on and active once it came up.

This may be my own foot-shooting since I was able to make a bootable
system on my sandbox using the same media (a clone hardware-wise so also
no EFI) -- there may have been some part of the /boot hierarchy that
didn't get copied over, and if so that would explain it.

Update: Indeed that appears to be what it was -- a couple of the *other*
files in the boot partition didn't get copied from the -STABLE build
(although the entire kernel directory did)....=C2=A0 I need to look at wh=
y
that happened as the update process is my own due to the dual-partition
requirement for booting with non-EFI but that's not your problem -- it's
mine.

Sorry about this one; turns out to be something in my update scripts
that failed to move over some of the files to the non-encrypted /boot....=


BTW am I correct that gptzfsboot did *not* get the ability to read
geli-encrypted pools in 12.0?=C2=A0 The UEFI loader does know how (which =
I'm
using on my laptop) but I was under the impression that for non-UEFI
systems you still needed the unencrypted boot partition from which to
load the kernel.
