stage 2 init script (...) not found

[shadowrylander]

Describe the bug
Unable to boot encrypted ZFS root using jakeday / linux-surface kernel, via module by anthe.

To Reproduce
Steps to reproduce the behavior:

1. Import surface.nix
2. Add kernel patch export_kernel_fpu_functions_4_14 or export_kernel_fpu_functions_5_3
3. Add config.boot.extraModulePackages = with config.boot.kernelPackages; [ zfs ];

Expected behavior
Expected encrypted ZFS root to boot as normal.

Additional context

Last Command: mounting [hostname]/root on /...

Fails With: stage 2 init script (...) not found

Last Error: An error occurred in stage 1 of the boot process, which must mount the root filesystem on '/mnt-root' and then start stage 2

Note that the stage 2 script does in fact exist in the nix store.

In addition, encrypted ZFS roots work on all non-Surface systems.

When something can't be found, check your hardware-configuration.nix; mine was missing the entry for the dataset with the nix store. Closing now.
