Upstream-Issue: NixOS/nix#10062

Is your feature request related to a problem? Please describe.

A colleague of mine tried to install Nix with /nix on an NTFS mount. He had no idea that this would not work out well for him.

The way that this goes wrong right now is that the install itself fails with "error: suspicious ownership or permission on /nix/store/<some storepath>". If you migrate your Nix store to NTFS later on the same kind of error starts showing up.

Describe the solution you'd like

I wish this was error condition that gets caught and named more clearly, with a dedicated error message, by the installer before it starts the actual install as well as by the Nix daemon on startup.

Describe alternatives you've considered

I guess the alternative is keeping things as they are.

Additional context

Some steps to reproduce this with a fresh install:

start out on a some Linux distro like Ubuntu with no Nix installed
mount some NTFS volume at /nix

sudo mkdir /nix
sudo mount -t ntfs /dev/vdb /nix

run the nix installer

sh <(curl -L https://nixos.org/nix/install) --daemon
answer install questions until install starts running

install fails

---- oh no! --------------------------------------------------------------------
Oh no, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.

:(

We'd love to help if you need it.
