For modules that are gated behind a mkEnableOption, it's reasonable to
just provide them to all Depot-built nixos systems without requiring
people to explicitly import them. This defines a special module called
`default-imports.nix` which imports these modules (currently just
tvl-cache.nix and automatic-gc.nix, as I'm being rather conservative
adding things here to avoid breaking anyone's system), then provides
that module as one of the `modules` passed at the top-level
nixos/eval-config invocation.

Currently in NixOS configuration using agenix secrets there is no
build time validation of secret paths - things fail at runtime (system
activation).
To prevent that, this CL makes the secrets part of the tree based on
the same configuration file used by agenix itself.
This guards against:
* agenix secrets.nix definition for a non-existent file
* age.secrets value in a NixOS config for a non-existent secret

The DynamicUser + Group configuration does not work as planned, thus
the systemd LoadCredentials feature is used instead which makes the
file (which itself is only readable by root) available in a
memory-backed location only readable by the service.
The secret is only available to `ExecStart` commands, so units using
this feature can not be used with pre/post units and the like if those
commands need secrets.
To accommodate this, the merge of configuration files has been moved
into the service launch script, which is now the ExecStart= process.
For details take a look at https://www.freedesktop.org/software/systemd/man/systemd.exec.html#LoadCredential=ID:PATH

Previously we served the dumb git HTTP protocol from code.tvl.fyi via
cgit. This CL disables this feature and instead runs josh in the same
location (by redirecting appropriately), but while also enabling
partial cloning of all subtrees of the depot.
For example, after this CL the following would result in an
independent clone of //nix/readTree:
git clone https://code.tvl.fyi/depot.git:/nix/readTree.git
Note that there are no josh workspaces configured at all for now,
these references are only for static depot subpaths.
Please refer to the documentation for josh for more information on
available kinds of josh filters.
Josh state is kept in a systemd state directory in /var/lib/josh and
backed up to Restic. Backing this up is necessary, as josh uses
stateful information to do things like tracking merges and rewriting
history per subtree appropriately to avoid cloned repositories ending
up in peculiar states.
