In the "Execute Command Example - Sudo Example", the used command is
defining environment variables prematurely, hence requiring the sudo
invocation to be made with the `-E` flag. However, this is not only
necessary but might have indesirable side effects, as the `-E` flag
forwards the whole environment to the subshell.
Commonly /tmp is set as noexec, as a result packer scripts
fail to run. In order to get around this one can set a
remote_path, whoever, remote path requires full filename
and path.
By making remote_path a combination of
remote_folder/remote_script we can change remote_folder
and keep the default script_nnn.sh
