Not much clever scripting needed. I use this (not on i386, so the raw
partition is c):

size="-B $(( 4482 * 1024 ))"
writecommand="growisofs -Z /dev/rcd0c=/dev/stdin"

ask_and_dump() {
    read -p "Type yes to start level 1 dump of $partition: " answer
    case $answer in
            dump -1 -u $size -f - $partition  | $writecommand 
            echo "$partition skipped..."

ask_and_dump "/home"
ask_and_dump "/usr"
