I tested this again today, but running "./make.sh downloadsrc" ended in
a bunch of error messages: "...mount point does not exist".

So I'm back to my previous solution from
https://community.ipfire.org/t/trying-to-build-188/11999/9

And I found that I only need ONE line:

...
   # If unshare is asked to terminate, terminate all child processes
   "--kill-child"
  )

mount --bind ${BUILD_DIR}/proc ${BUILD_DIR}/proc

 fi

while [ $# -gt 0 ]; do
  case "${1}" in
...

Right now I wouldn't add anything. This is too mysterious (to me). Its
working - but I don't know why.

In a few days the LTS-update for Ubuntu 24.04 LTS will be available -
its scheduled for August 29. I'll test this update and then we'll see.

Thanks! I'm testing...
