Consider following XDG base directory specification on Linux

[bkoropoff]

Putting everything in ~/.<appname> has been considered bad practice on Linux for a while.

https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html

• Configuration files usually go in ~/.config/
• Cache files (anything it's safe to delete) usually go in ~/.cache/
• Data files (e.g. saves) usually go in ~/.local/share/

This keeps the home directory clean, lets backup apps only back up important files, lets the cache directory be cleared to reclaim space, etc.

My main concern about changing anything like this is if it will cause problems for existing users

[bkoropoff]

The code should detect an existing ~/.dsda-doom directory and continue using it for config and save games if it's present. That's how a lot of other Linux apps migrated to the XDG spec.

I remember submitting a patch for this to PrBoom+, only problem is the logic prioritized the path under home directory rather than the default.

If I'm not mistaken, PrBoom+ has already implemented this in coelckers/prboom-plus#470
