[Bug]: 7 Days to Die server doesn't start, Permission denied.

[Dumuthy]

User story

Trying to install 7 Days to Die server using the vinanrra/7dtd-server image, which relies on lgsm for internal control actions of the server such as starting and stopping it. During install, everything goes smoothly up intill the actual gameserver attempts to start using the ./sdtdserver start command. At which point, the server fails to start with a "Permission Denied" error. Logs below.

Further information

I chose Other for the distro because I'm running docker on Arch. I know, I know, don't run servers on bleeding edge distros. I'm working on that. However, I see no reason why this should be making a difference here. Also, my docker-root directory is a 5TB RAID volume mounted at /mnt/Storage, which I have ensured has correct permissions by running sudo chown -R 1000:1000 /mnt/Storage after the permission denied issue occurred. Docker is set to run in rootless mode.

Since the ./sdtdserver start and the ./sdtdserver debug commands equate to the same thing, but the latter gives details about the starting process, I've pasted logs of the debug command. Every other command that I have tried works perfectly fine, including update, update-lgsm, install, details, monitor, and validate. I'm not certain if any other information is needed, but I'm happy to provide it upon request.

Steps to reproduce

1. Open Dockge in my browser and copy/edit config.yaml for the container.
2. Click deploy container
3. Watch everything succeed without so much as a single warning or error up until the ./sdtdserver start command is run in order to actually initiate the server instance within the container.
4. Cry.

Update, this is not an issue with how the container is deployed. Dockge, Portainer, and even just command line will not work. Same results no matter what method is used to deploy the container. It's also not the permissions of the host file system, as all volume variables were removed and I allowed Docker to decide where volumes would be placed.

The issue appears to be in the "7DaysToDieServer.x86_64" executable permissions. When checking the permissions after logging into the container with docker exec -it 7days sh, hunting the file down in ~/serverfiles, and running ls -l on the file, the result is...
-rwxr-xr-x 1 sdtdserver sdtdserver 14800 Mar 31 15:57 7DaysToDieServer.x86_64

I do not know what they should be, so I'm leaving this open for now, as I don't want to attempt to change the permissions and create more issues that might make the problems worse.
