NFS mounts not working in (at least) VM

[tobimai]

I tried generating a VM to test a config of mine, and it worked find in general (users, installed packages etc. ). Only the NFS mounts were not in the VM, and there was no error.

In a "proper" VM the config works as expected and mounts the images.

This is the part of my config:

    fileSystems."/mnt/nas-xxx" = {
        device = "192.168.xx.xx:/mnt/xxx/xxx";
        fsType = "nfs";
    };

And i used this command to create/start the VM: nixos-generate -c config.nix -f vm --run

ah yeah, nixos ignores fileSystems options in vms. seems more like a nixpkgs issue to me and you would need to investigate there if there is some kind of override mechanism for that

Try this:

    fileSystems."/mnt/nas-xxx" = lib.mkForce {
        device = "192.168.xx.xx:/mnt/xxx/xxx";
        fsType = "nfs";
    };

lib.mkVMOverride might also work
