What about that:

$ cat webPort
WEB_PORT=8888

And in the service:

EnvironmentFile=/some/path/webPort
ExecStart=vm/squeak -vm-sound-null -vm-display-null -mmap 1024m -eden 16m ss.image run.st $WEB_PORT

Even better yet:

$ cat /etc/default/squeaksource
WEB_PORT=8888
IMAGE_PATH=/path/to/ss.img
STARTUP_SCRIPT=/path/to/run.st
VM_OPTS=-vm-sound-null -vm-display-null -mmap 1024m -eden 16m

and in the Service:

EnvironmentFile=/etc/default/squeaksource
ExecStart=/path/to/vm/squeak $VM_OPTS $IMAGE_PATH $STARTUP_SCRIPT $WEB_PORT

Because then you do not need to "systemctl daemon-reload" each time you change one of the thins in the env file…
