in thread why does perl-suid not mount

So the program cannot determine what the $home of the real user may be...
sudo normally sets $SUDO_UID and $SUDO_USER to the calling (original) user, which you could query in your script.

    That was a great hint. I modified the script to check for $SUDO_UID and it runs like a charm.

    Thanks a lot.

    After tidying it up, I'll put it on github in case anybody faces similar challenges.
