https://github.com/NixOS/nixpkgs/pull/131760 was made to avo a speicific configuration conflict that errored out for multiple definitions of "/" when the installer where overlayed on any existing host configuration. --- Problem 1: It turns out that in also other mountpoints can coflict. Solution 1: use `mkOverride 60` for all mountpoints (even for the ones unlikely causing confilct for consistency sake) --- Problem 2: It turns out that on an installation media for a fresh machine (before formatting), we usually don't have any devices yet formatted. However defining for example `fileSystems.<nme>.device = "/dev/disk/by-label/...", in newer versions of nixos, seems to make the system startup fail. Similarily waiting for a non-existent swap device does not make the startup fail, but has a 1:30 min timeout. Solution 2: For an installation medium, soft-override ("unless users know what they are doing") the entire `fileSystems` and `swapDevices` definitions.
