As the "zfs clone" is carried out in the brand-specific script, i think

/usr/src/lib/brand/solaris10/zone/clone.ksh

is not capable of a zfs copy at the moment.

Ok, i am thinking of this:
->clone.ksh ( origin: local OI installation )

1. Other brand clone options are invalid for this brand.
   while getopts "R:s:Xz:m:" opt; do
   case $opt in
   R) ZONEPATH="$OPTARG" ;;
   s) case "$OPTARG" in
   *@*) # Full snapshot name was provided, or just "@snap" # Split this into dataset name (even if empty) and # snapshot name (also may be empty)
   SNAPNAME="`echo "$OPTARG" | sed 's/^[^]*//'`"
   REQUESTED_DS="`echo "$OPTARG" | sed 's/\([^]*\).*$/\1/'`"
   ;;
   */*) # Only dataset name was passed, so we will make a # snapshot there automatically and clone off it
   SNAPNAME=""
   REQUESTED_DS="$OPTARG"
   ;;
   *) # Only snapshot name was passed, so we will clone # the source zone's active ZBE and this snapshot
   SNAPNAME="$OPTARG"
   REQUESTED_DS=""
   ;;
   esac
   ;;
   X) NO_SYSUNCONFIG=yes ;;
   z) ZONENAME="$OPTARG" ;;
   m) DOZFSCOPY=yes ;;
   *) fail_usage "";;
   esac
   done

...

1. do clone
   BENAME=zbe
   BENUM=0
   while [ $BENUM lt 100 ]; do
   if [ -z "$DOZFSCOPY" ]; then
   /usr/sbin/zfs clone $ACTIVE_DS@$SNAPNAME $zpds/$zpname/ROOT/$BENAME ;
   else
   /usr/sbin/zfs send $ACTIVE_DS@$SNAPNAME | /usr/sbin/zfs receive -v $zpds/$zpname/ROOT/$BENAME ;
   fi
   if [ $? = 0 ]; then
   break
   fi
   BENUM=`expr $BENUM + 1`
   BENAME="zbe$BENUM"
   done

hmm. it seems that i can't find the correct source of my local file

/usr/lib/brand/ipkg/clone

it is NOT

illumos-gate/usr/src/lib/brand/solaris10/zone/clone.ksh
