The background is that there are at least two distributions with very
different host fs layouts. Those would be NixOS and GNU Guix.
For example, on NixOS, /lib/modules does not exist, it can instead
be found at /run/current-system/kernel-modules/lib/modules where
/run/current-system/kernel-modules is a symlink into /nix/store.
Within the modules directory, again on NixOS, there are more links
into the /nix store.
So to support alternate host fs layouts it is now possible to specify
the lib/modules host path and in addition specify extra mounts.
