This should, of course, be ..

#!/bin/sh
rmdir /usr/local/jails/basejail/usr/src
mv /usr/src /usr/local/jails/basejail/usr/src
for JAIL in {list-your-jails-here}
do
        JAIL_ID=`jls | grep $JAIL | awk '{ print $1 };'`
        echo "Updating: ${JAIL}"
        jexec ${JAIL_ID} mergemaster -scvi
done
mv /usr/local/jails/basejail/usr/src /usr
mkdir /usr/local/jails/basejail/usr/src
