I have one machine that is running 18 zones (and the global one to boot).
When the global zone has been updated, the rest of the zones need to be updated as well. Each and every one, one by one.
Which is why I wrote the following script which I wish to share. If you find it useful, enjoy :) If you improve it, please do tell me, and please share the improvements - it's not a requirement, but it's a nice gesture.

# Description : The intent of this script is to run boot-environment updates on OpenIndiana.
# It should make certain that some things are "kosher", but it doesn't attempt any
# damage control at the moment. That is done via the ZFS snapshots which are an
# integral part of the update process.
#
# Version 1.0
PATH=/usr/gnu/bin:/usr/bin:/usr/sbin:/sbin
export PATH
BEMNT=/bemnt # where we want to mount the boot environment after update
MYID=$(whoami)
if [ "${MYID}x" != "rootx" ]
then
echo "Must be root to run this script."
exit 1
fi
# All kinds of tests on the $BEMNT
#
# does it exist?
if [ ! -d ${BEMNT} ] ; then
mkdir ${BEMNT}
RV=$?
if [ $RV -ne 0 ] ; then
echo "Could not make directory ${BEMNT}"
exit 1
fi
fi
# is it empty ?
if [ "$(ls -A ${BEMNT})" ] ; then
echo "${BEMNT} is not empty. Either another update is being performed,"
echo "the last update failed miserably, or you have chosen an unwise"
echo "location to use as the mount-point for the boot evironment update."
echo "Please investigate, revise and repeat."
exit 2
fi
RILI=$(zoneadm list -cv | grep -v STATUS | grep -v global | awk '{printf("%s ",$4);}')
BENAME=$1
if [ "${BENAME}x" == "x" ] ; then
echo "Usage: $0 bename"
echo "Where bename is the boot environment name you wish to use."
exit 3
fi
echo "Starting update of GLOBAL environment"
pkg image-update --be-name ${BENAME}
if [ "${RILI}" ] ; then
echo "Mounting boot environment"
beadm mount ${BENAME} ${BEMNT}
echo "Now, updating the zones, one by one..."
for ZUP in ${RILI} ; do
ZNA=$(echo $ZUP | gawk -F '/' '{print $4}')
echo "Updating $ZNA"
pkg -R ${BEMNT}${ZUP}/root image-update
done
echo "Unmounting boot environment"
beadm umount ${BENAME}
else
echo "There are no zones, so there's nothing to do here. The global is already updated."
fi
# if the ${BEMNT} still exists, we should rmdir it, since we don't want an empty arbitrary directory
# just lying around..
rmdir ${BEMNT}
echo "Done."
echo
echo "It would most probably be a very good idea to reboot at this moment. Thank you :-)"
echo
exit 0

I hope you find it useful - I did :)
