A few notes: * The `echo hi` is needed to make sure that a file that can be read by `nix log` is properly created (i.e. some output is needed). This is known and to be fixed in #6051. * We explicitly ignore the floating-CA case here: the `$out` of `input3` depends on `$out` of `input2`. This means that there are actually two derivations - I assume that this is because at eval time (i.e. `nix-instantiate -A`) the hash of `input2` isn't known yet and the other .drv is created as soon as `input2` was built. This is another issue on its own, so we ignore the case here explicitly.
