We currently evaluate every target twice -- once when the depot pipeline
is built and once when actually running the build step in question. Nix
evaluation is quite slow especially given heavy use of import from
derivation in depot, so avoiding the second evaluation is desireable.
Evaluating a derivation yields a `drv` file in the nix store which can
be passed to `nix-store --realise` in order to build it eliminating the
need to wait for evaluation. We can obtain the path to the `drv` file
while building the pipeline via `target.drvPath` and remember it for the
build later.
However we need to work around a flaw (or oversight) in Nix's dependency
tracking via string context: This is based on derivations, not output
path (because this is what evaluation deals with, likely). This is no
problem per se, but an issue is that Nix can't express a dependency on
a `drv` file without any of its output paths. This means for us that we
either have to build all output paths at evaluation time (which we don't
want, obviously) or to deal with the fact that the `drv` file we need
may be garbage collected at any moment after discarding the string
context -- then nix is unable to track the reference from the pipeline
to the `drv` file in the store.
So to prevent a race condition between the pipeline and the garbage
collector we fall back to the normal nix-build invocation as we did
before.

This is a bit of an under-documented feature, but if the "tag" field for
a gerrit review starts with the string
"autogenerated:<something>~<something-else>", only the last comment per
instance of <something> will be shown by default on the CL page (with
the rest viewable by toggling the "Show all entries" switch). The idea
behind the "<something-else>" tag is to be used for the "type" of
comment within a particular system - gerrit's documentation gives the
example of one tag for "the build is running" and another for "the build
has finished, here's the result".

We'll need to do a DNS switchover, likely with a short amount of

It would be possible to avoid this by provisioning a cert manually
pre-hoc through the DNS challenge and then configuring whitby to use
that, however I simply don't have time for that right now and the
Google Cloud Project for Nixery is going away in O(days) for $reasons.
