Thank you.

So you have replaced

  grep -q /live/findiso /proc/mounts && umount /root/live/findiso

with

  [ ! -z ${mountpoint} ] && umount /root/live/findiso

It seems more fragile to me than what the original patch did (although
it did in a way I did not like); but maybe you can explain us why this
new check is sufficient and/or better suited than the old one?

Other than that, this patch is fine with me.
