This naughty RealTek wireless module crashes my machine. I'm also moving other
`boot`-prefixed options out of `hardware.nix` and into `default.nix`. In
general, I'm not *really* a fan of the distinction between the two files in the
first place.

```shell

I had to rollback to the initial NixOS version and try again.

Strange start to my Monday where I spent ~2h debugging my hanging
NixOS. Strangely I'm not sure I made any changes to my configuration to trigger
this, and I was finding this hard to reproduce:
- graphical X sessions hung (once when opening Chrome)
- TTYs hung (during `nix-build` and `rebuild-system`)
Per kn's recommendations whenever a system is hanging, see if it's reachable
over the network (e.g. SSH). Since I didn't have my laptop, I downloaded Termius
on my iPhone, which I used to mosh into ava, which is a surprisingly nice UX.
I suspect my machine (with only 8GB of RAM) was OOMing, but I'm not
certain. Thanks to grfn I installed `earlyoom`. For more commentary, check-out
Profpatsch's blog post about this: https://profpatsch.de/notes/preventing-oom
What went well:
- Thankfully I installed a Matrix client on my iPhone last week, which allowed
me to troubleshoot with the #tvl folks
AIs:
- I'd like some instrumentation like Prometheus, Loki (`journald`, `dmesg`), so
that I can accumulate troubleshooting information that isn't destroyed when I
reboot my machine (which I did 1/2-dozen times today).
- Consider adding `git` metadata to `system.nixos.label` to get more useful
information in a GRUB/EFI context.
More unknowns:
- Why can't I switch back to EFI (from GRUB) for my bootloader?

So it turns out that there's a NixOS *and* a home-manager module for
redshift. While I couldn't get the NixOS module to WAI, the home-manager version
seems to work just fine.
I'm hard-coding the lat/lon for now, because I still can't get "geoclue2" to
work, but I'm not interested in debugging that at the moment.

This support reverse-DNS lookups.
I encountered a problem where I accidentally deleted my instance's
`nat_ip` (external, ephemeral IP). I needed to run...
```shell
terraform apply -replace=google_compute_instance.diogenes
```
...which invalidates terraform's local cache of the state. I believe this used
to be called `terraform taint`. Things are mostly WAI, with one known issue:
quasselcore and billandhiscomputer.com complain about missing SSL certs, but I
believe this is a race-condition. Calling...
```shell
systemctl restart quassel.service
```
...resolves the issue for quassel. Unfortunately the same doesn't work for
nginx.service, but after a bit of time https://billandhiscomputer.com "just
works". Clearly I'm not sure what's going on here. At least not yet...
