I'm trying to setup a factorio headless server in such a way that all modifiable server data lives in a dedicated directory, so that I can run multiple instances of the server in parallel, or at the very least switch between them without crosstalk in config or save files.
For this I marked the factorio directory as read-only and start the binary with "-c" to give it a writable config file at another location.
The whole thing seems to work fine as far as I can say with only a few minutes of testing, but I'm getting a non-fatal error in the server log on startup and shutdown that I don't get with a standard "portable" setup where config and all write data lives in the factorio directory itself.

- I started in a dedicated directory
- I downloaded the current (0.14.21) headless server
- I extracted the headless server as a tar.gz file
- I recursively changed all permissions for the resulting factorio directory to read-only by doing
Code: Select all
chmod a-w -R ./factorio - I created a second directory "s1" next to the factorio one to hold the savegames and config file
- Directory layout now looks like this:
Code: Select all
ls -alh dr-xr-xr-x [...] factorio/ -rw-r--r-- [...] linux64.tar.gz drwxr-xr-x [...] s1/ - In s1, I created a vanilla config.ini by copying in an existing one
- I modified it to point its write-data path to the current directory. The contents of that config.ini are this:
