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

The irccat module uses DynamicUser, so to grant permission to it a new

I have some vague memory of DynamicUser + Group not behaving as one
would expect, but we'll see what happens.

Since GCP nuked us, the backups are now moving to GleSYS'
S3-compatible object storage.
This refactors the restic module to support S3-compatible storage
instead of GCP, and switches to the appropriate new secret paths.
The secrets were placed on whitby manually and I verified that the
backups work.
This fixes b/157

First step towards giving depot modules the ability to declare their
own backup directories by moving all restic configuration into a new
module and adding a NixOS option for inclusion/exclusion paths for
backups.
This still keeps all backup paths within the whitby config.

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.

flipping over nixery.dev
