Would it be possible to make Zero-K.exe to use the standard linux directories?
This would imply the following changes:

• Store the game preferences files (player setup, hotkeys, unit settings, campaign progress) in $HOME/.config
• Store the game downloaded files (maps, engine, replays, whatever else the game downloads post-install) in $HOME/.cache

This would make packaging Zero-K for linux distros a whole lot easier to accomplish, as well as to achieve compliance with distro requirements for package behavior. This would, in turn, help with ZK popularity on linux desktops quite a bit.

I am quite sure that a good way to detect if this behavior should be triggered is to check if the directory where Zero-K.exe is located is writable. There is already a check for it in the code, so the modifications would be truly minimal.

Once this is done I can make packages for at least a few popular distros.
