The bug reappeared after all, and the fix introduced a different bug. We
want to release 2.27 imminently so there is no time to do a proper fix,
which appears to require a larger reworking. Hopefully we will have it
for 2.28, however.
This reverts commit c98525235f.
"content-address*ed*" derivation is misleading because all derivations
are *themselves* content-addressed. What may or may not be
content-addressed is not derivation itself, but the *output* of the
derivation.
The outputs are not *part* of the derivation (for then the derivation
wouldn't be complete before we built it) but rather separate entities
produced by the derivation.
"content-adddress*ed*" is not correctly because it can only describe
what the derivation *is*, and that is not what we are trying to do.
"content-address*ing*" is correct because it describes what the
derivation *does* --- it produces content-addressed data.
This fixes dynamic derivations, reverting #9081.
I believe that this time around, #9052 is fixed. When I first rebased
this, tests were failing (which wasn't the case before). The cause of
those test failures were due to the crude job in which the outer goal
tried to exit with the inner goal's status.
Now, that error handling has been reworked to be more faithful. The exit
exit status and exception of the inner goal is returned by the outer
goal. The exception was what was causing the test failures, but I
believe it was not having the right error code (there is more than one
for failure) that caused #9081.
The only cost of doing things the "right way" was that I had to
introduce a hacky `preserveException` boolean. I don't like this, but,
then again, none of us like anything about how the scheduler works.
Issue #11927 is still there to clean everything up, subsuming the need
for any `preserveException` because I doubt we will be fishing
information out of state machines like this at all.
This reverts commit 8440afbed7.

I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests
- Concepts is harder to understand, the documentation makes a good
unit vs functional vs integration distinction, but when the
integration tests are just two subdirs within `tests/` this is not
clear.
- Source filtering in the `flake.nix` is more complex. We need to
filter out some of the dirs from `tests/`, rather than simply pick
the dirs we want and take all of them. This is a good sign the
structure of what we are trying to do is not matching the structure
of the files.
With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests
functional/
installer/
nixos/
```
