Subject: [PATCH] multipath-tools: specify `etc_prefix` (as otherwise it
 defaults to `prefix` which points to the read-only nix store), and it
 properly reads the configuration file generated by
 `nixos/modules/services/networking/multipath.nix` at `/etc/multipath.conf`

See: https://github.com/opensvc/multipath-tools/commit/98236a2be45d4e1e34debff785a08c3d1f37d0ed
