Download to /tmp means docker mounted /data mount point insufficient, install fails

[xaphod]

It took me a fair while & going thru source to figure this out. I run the docker image on Synology unit. Your helpful README indicates to add a mount point for the container's /data folder. If I do only that, install fails with

curl: (23) Failure writing output to destination

Turns out this is because your install script wants to download the ZIP file to /tmp. The workaround for me was to create another mounted folder for /tmp.

Suggestion: try touching a file in /tmp and if that fails, write the downloaded ZIP file to /data instead.

Thank you very much for this great repo & container, my son really appreciates your work 👍

I'm actually surprised I still have it downloading to /tmp since on Java edition image I had long since changed that for the reason you found.

There is an env var TMP_DIR that can be set, as you might have seen. In fact, I might default that to a /data/.downloads directory instead.
