Code review comment for ~mwhudson/debian-cd/+git/ubuntu:no-jigdo

Also, further down we have:

case $DIST in
  bionic|focal)
    # temporary hack until such time as we can upgrade all builds to 1.4.2
    new_xorriso="/home/cdimage/xorriso/xorriso-1.2.4/xorriso/xorriso"
    if [ -x "$new_xorriso" ]; then
      export amd64_MKISOFS="$new_xorriso"
      export arm64_MKISOFS="$new_xorriso"
    fi
    ;;

And on the new server, it's:

cdimage@cdimage-master:~/cdimage/www/full$ ls /home/cdimage/xorriso/xorriso-1.2.4/xorriso/xorriso
ls: cannot access '/home/cdimage/xorriso/xorriso-1.2.4/xorriso/xorriso': No such file or directory

So are any of these variables doing anything at all?
