This is useful when first setting up a device. Call `passwd` afterwards to
imperatively change the password.

Shared between `ava` and `tarasco`. Also define `lib/default.nix` to share
utility functions like `usermod` between NixOS configurations.

I broke LVM (Logical Volume Manager - maybe?) when I did the following:
```shell
$ HOSTNAME=ava sudo rebuild-system
$ sudo reboot now
```
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?
