Usage of unsafeDiscardStringContext breaks soundness for registration information #407
Description
Since 8474838 — registration information is not available neither on the host neither on the guest if you are not using a store disk.
This is because string context has been discarded and registration information is not enforced to remain on the host via alternative mechanisms, breaking on one hand the store invariants of Nix and on the other hand crippling Nix inside the VMs.
