The placement of this option under `nix` was misleading, as it is not
configuration of the Nix daemon, but rather configuration of the NixOS
boot process and how it mounts the Nix store. As such, make it an option
of `boot` to clarify what it actually affects, and imply that it will
only take effect on a reboot.
Since it no longer has the context of nix, adjust the name to include
it.
Or else systemd-oomd gets marked as failed due to
"Userspace Out-Of-Memory (OOM) Killer was skipped because of a failed condition check (ConditionControlGroupController=v2)."
and cause the system to enter degraded state.

Currently paths are handled by `types.package`, whose semantics are a
bit of a mess. In particular, it converts path values to derivations
using `toDerivation`, which will lead to problems when flake `outPath`s
become paths in https://github.com/NixOS/nix/pull/6530.
This change makes the "incompatible changes" section in the above PR
obsolete: `nix.registry.nixpkgs.flake = nixpkgs;` works as expected (the
flake is copied to the store).
Hided home/trash/network desktop icons by default.
Also changed their default logo settings (cs_info and menu), so what we
should modify to cinnamon-symbolic is now linuxmint-logo-ring-symbolic.
We are lucky, linuxmint-logo-ring-symbolic only appears in a few other
places and non of them are useful, menu@cinnamon.org/settings-override.json
simply won't work because cinnamon-common doesn't know that file.
Also set default cursor theme, this package now directly provides those
cursor themes. And, we now default to the Mint-Y-Aqua theme.
We don't need both wget and curl, so let's use only curl (which is
part of a minimal NixOS closure, unlike wget).
Logging to the console is helpful for debugging.
Instances without SSH keys configured will receive a 404 from the
metadata server when attempting to fetch an SSH key. This is not an
actual problem though, and shouldn't result in the service failing.
If the metadata server cannot be reached, the script will fail at an
earlier stage when attempting to get authentication data.
This also removes automatic enablement/mounting of instance store swap
devices and ext3 filesystems. This behaviour is strongly opinionated
and shouldn't be enabled by default.
The unionfs behaviour never took effect anyway, because the AMI
manifest path only exists for instance store-backed AMIs, which have
not been supported by nixpkgs since
84742e2293 (2019).
