# XDG "compliant" programs
  .config/ etc/

  .cache/ var/cache/

It's amusing that modetc goes through all this effort to twist dotfiles into the XDG half-solution, and here I am using symlinks through /dev/shm/xdg/* to warp XDG into sort-of working in an actual heterogeneous environment.

Because XDG by itself is a failure beyond trivial cases.
