-sharp It is highly advisable to create own systemd services or udev rules
-sharp to run scripts during boot instead of using this file.

-sharp In contrast to previous versions due to parallel execution during boot
-sharp this script will NOT be run after all other services.

in addition to the background execution mentioned above, give it a try. and do you want to make sure that the direct / usr/opt/etlive-page-01/server operation is OK? Check whether there is a place in the program to write dead calls to the relative directory (the current directory)
