[solved] game.write_file does not work at all

[mpk]

hey everyone,
I'm trying to write data with game.write_file(path, data) however it does not work at all, neither in a mod nor when I run it via the ingame console with /c game.write_file('/home/user/text.txt', 'hello there')

when exactly does the game flush the written data? right after the call or does it cache all calls to write_data and waits for the game to close?
I'm on ubuntu, is there anything special I need to be aware of other than sufficient permissions?

It should write the file immediately. If you are running this in multiplayer, try with the command /c game.write_file("text.txt", "hello there", false, 1)

Yup there it is, that solves it. Factorio file writes seem to take this directory always as their root
This should be noted in the api wiki.
