WIP: Document the design of Nix
...
The current docs are all "how to do things" and no "what is Nix" or "why
are things the way they are".
I see lots of misconception on the wider internet, and I also think we
would benefit from a "living document" to answer some questions people
currently turn to the thesis for.
I think a new section of the manual can address all these issues.

it is out of date, all over the place in level of detail, is really

a reference manual.

Don't use -load_all on darwin

That flag breaks `-lc++fs` (introducing a duplicate symbol for some
reason). Besides, it was apparently needed for bzip2, but we're not using bzip2
anymore.

Make moveFile
more atomic
...
Rather than directly copying the source to its dest, copy it first to a
temporary location, and eventually move that temporary.
That way, the move is at least atomic from the point-of-view of the destination

Re-implement the recursive directory copy
...
The recursive copy from the stl doesn’t exactly do what we need because
1. It doesn’t delete things as we go
2. It doesn’t keep the mtime, which change the nars
So re-implement it ourselves. A bit dull, but that way we have what we want

rename: Fallback to a copy if the filesystems mismatch
...
In `nix::rename`, if the call to `rename` fails with `EXDEV` (failure
because the source and the destination are in a different filesystems)
switch to copying and removing the source.
To avoid having to re-implement the copy manually, I switched the
function to use the c++17 `filesystem` library (which has a `copy`
function that should do what we want).

derivation-goal.cc: remove bmCheck custom return branch on buildDone
...
Once a derivation goal has been completed, we check whether or not
this goal was meant to be repeated to check its output.
An early return branch was preventing the worker to reach that repeat
code branch, hence breaking the --check command (#2619 ).
It seems like this early return branch is an artifact of a passed
refactoring. As far as I can tell, buildDone's main branch also
cleanup the tmp directory before returning.

redirects to
https://hydra.nixos.org/build/183877779/download/1/manual/contributing/hacking.html ,
which gives me a "500 Internal Server Error". Not super useful =(
Feel free to ignore if someone's working to fix the 500 I was running
into.
