Most of the output was in the screenshot just above that, and I guess I found a workaround
that should suffice (will test more today), but for the sake of completeness, here goes:
The old BE was OmniOS bloody updated a month ago (20150602Z070407), new one with an updated pkg program was made yesterday, starting as the old one's clone (export BENEW=omnios-20150701Z065339-test) and the relevant tree was mounted into "/a" with my splitroot scripts from github:
###############################

omnios-20150701Z065339-test does not exist or appear to be a valid BE.

###############################
So, the tree above is mounted. Updating pkg under /a altroot itself (note the script does this via "pkg -R /a update pkg", but in the example below I do it via chroot to verify it generally works for this):
###############################
:; chroot /a /usr/bin/pkg -R / update pkg

###############################
Now, trying to update packages inside that altroot in different ways...
What the script tries in the chroot:
###############################
:; chroot /a /usr/bin/pkg -R / image-update --no-refresh --accept --deny-new-be --no-backup-be
Creating Plan (Package planning: 425/427): /
pkg update: The proposed operation cannot be performed on a live image.
###############################
Trying to cheat with a non-verbatim "/" altroot string in the chroot:
###############################
:; chroot /a /usr/bin/pkg -R /// image-update --no-refresh --accept --deny-new-be --no-backup-be
pkg update: The proposed operation cannot be performed on a live image.
###############################
Trying the two other ways the script attempts (original BE's old pkg over a new BE's packages)
###############################
:; /usr/bin/pkg -R /a image-update --no-refresh --accept --deny-new-be --no-backup-be
Checking that pkg(5) is up to date -
WARNING: pkg(5) appears to be out of date, and should be updated before
running update. Please update pkg(5) by executing 'pkg install
pkg:/package/pkg' as a privileged user and then retry the update.
###############################
###############################
:; /usr/bin/pkg -R /a image-update --accept --deny-new-be --no-backup-be
WARNING: pkg(5) appears to be out of date, and should be updated before
running update. Please update pkg(5) by executing 'pkg install
pkg:/package/pkg' as a privileged user and then retry the update.
###############################
Finally, reading through the sources at /usr/bin/pkg and /usr/lib/python2.*/vendor-packages/pkg/ I tracked the error message to decision points to is_liveroot() to obscure envvars and/or configuration settings that cause some boolean regarding required new BE's to be true or false regardless of package-reboot settings.
Here is a piece which made me think it is intended for debug and so might not be a piece of committed API (would love to be wrong on this point): https://java.net/projects/ips/sources/pkg-gate/content/src/tests/api/t_bootenv.py#62
So, using PKG_LIVE_ROOT envvar, but no -R for altroot - no banana:
###############################
:; PKG_LIVE_ROOT=/ chroot /a /usr/bin/pkg image-update --no-refresh --accept --deny-new-be --no-backup-be
pkg update: The proposed operation cannot be performed on a live image.
###############################
Using both PKG_LIVE_ROOT envvar and -R for altroot - this is what ultimately succeeded, though only with a non-verbatim-"/" root directory string in this envvar:
###############################
:; PKG_LIVE_ROOT=/ chroot /a /usr/bin/pkg -R / image-update --no-refresh --accept --deny-new-be --no-backup-be
pkg update: The proposed operation cannot be performed on a live image.
:; PKG_LIVE_ROOT=/// chroot /a /usr/bin/pkg -R /// image-update --no-refresh --accept --deny-new-be --no-backup-be
