  # Our glibc will look for the cache in its own path in `/nix/store`.
  # As such, we need a cache to exist there, because pressure-vessel
  # depends on the existence of an ld cache. However, adding one
  # globally proved to be a bad idea (see #100655), the solution we
  # settled on being mounting one via bwrap.
  # Also, the cache needs to go to both 32 and 64 bit glibcs, for games
  # of both architectures to work.
