d100c1f49f feat(wpcarro/ava): Support earlyoom
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?

SSH is feeling a bit too laggy; let's try `mosh`.

I like httpie's UX better than `curl`'s.

More tools I didn't know I'd ever become acquainted with until I started
supporting Windows Servers: remmina - for RDPing.

This allows me to use my device as a router (or in Tailscale terms: as an "exit
node").

04204c3863 feat(wpcarro/ava): Set timezone on ava to L.A.
ava isn't a laptop, so we shouldn't support roaming timezones. Let's hard-code
this to L.A. for now.

Strange commit title, but true. Make sure nathan (my MBP) can SSH into ava (my
NixOS box at work).
