User story

As a server administrator, I want the startup command to be fixed so that servers will start from update 8 forward

Game

Satisfactory

Linux distro

RedHat 9

Command

command: start

Further information

With update 8 SF got switched from UE4 to UE5. Thus the server executable was renamed. When trying to start it tries to execute UE4Server-Linux-Shipping which isn't available anymore. From now on it will start with UnrealServer-Linux-Shipping.

Until now Update 7 is still in stable. Normally experimental Update releases swap around 1 month after release to stable, but this could be hold longer due to the Engine upgrade and the potential of a ton of things. So it would need to check if the UE4 executable is still available and start that or go to the UnrealServer one.

The new FactoryServer.sh also confirms this swap:

#!/bin/sh
UE_TRUE_SCRIPT_NAME=$(echo \"$0\" | xargs readlink -f)
UE_PROJECT_ROOT=$(dirname "$UE_TRUE_SCRIPT_NAME")
chmod +x "$UE_PROJECT_ROOT/Engine/Binaries/Linux/UnrealServer-Linux-Shipping"
"$UE_PROJECT_ROOT/Engine/Binaries/Linux/UnrealServer-Linux-Shipping" FactoryGame "$@"

Relevant log output

[sfserver@mycloud ~]$ ./sfserver start
[ FAIL ] Starting sfserver: executable was not found
* /home/sfserver/serverfiles/Engine/Binaries/Linux/UE4Server-Linux-Shipping
[sfserver@mycloud ~]$ ls -lah /home/sfserver/serverfiles/Engine/Binaries/Linux/*-Linux-Shipping
-rwxr-xr-x. 1 sfserver sfserver 173K Jun 14 14:01 /home/sfserver/serverfiles/Engine/Binaries/Linux/UnrealServer-Linux-Shipping
[sfserver@pornsec-hub ~]$

Steps to reproduce

Switch to Update 8 beta ( add branch="experimental" to common.cfg config file)
Install or upgrade the server
Start the server with ./sfserver start

Workaround for now:

Swap executable variable in config (_default.cfg or common.cfg when copied over)

From

## Game Server Directories
[...]
executable="./UE4Server-Linux-Shipping"
[...]

Into

## Game Server Directories
[...]
executable="./UnrealServer-Linux-Shipping"
[...]
