This makes it clear that this should be used with care
It is potentially more expensive to create the full object, therefore it should be discouraged by its longer name
This listing is implemented based on the basic listing, where each item is turned into the bigger machine class
This avoids re-initializing the Flake object deep in the tree, which in turn leads to issue when overriding the Flake for testing, eg the URl would reset.
I ran into this error when trying to run `opendkim-genkey` in a vars
generator:

As we allow `/bin/sh` in the nix build sandbox, I assume we're OK
allowing it here as well?
... for now only when updating a machine (not when installing)
Whenever the user clicks on the update button in the machine view, and only if user input is needed for some missing vars, the user will be forwarded to a vars page.
Invalidation doesn't need to be done after each generator is executed.
We cannot interpolate values from other generators into another
generator. The generators are executed in order. The finalScript of each
generator stays constant.
After the complete closure is generated the caller of generate may
decide to invalidate the flake cache
