Without this commit, unsetting any of the `services.kubo.settings` options does not reset the value back to the default. This commit gets rid of this statefulness.
This is achieved by generating the default config, applying the user specified config options to it and then patching the `Identity` and `Pinning` config options from the old config back in. This new config is then applied using `ipfs config replace`.
The only remaining stateful parts of the config are the `Identity` and `Pinning.RemoteServices` settings as those can't be changed with `ipfs config replace`. `Pinning.RemoteServices` also contains secrets that shouldn't be in the Nix store. Setting these options wasn't possible before as it would result in an error when the daemon tried to start. I added some assertions to guard against this case.
Trivial conflict in release notes, except that the xml/docbook parts
are horrible for (semi-)automatic conflict resolution.
Fortunately that's generated anyway.
Adds a new option to the virtualisation modules that enables specifying
explicitly named network interfaces in QEMU VMs. The existing
`virtualisation.vlans` is still supported for cases where the name of
the network interface is irrelevant.
`autosuspend` is a daemon that periodically runs user-defined checks to
verify whether the system should be suspended. It's already available
in nixpkgs. This adds a NixOS module which starts the daemon as a
systemd service.

following the plan in https://github.com/NixOS/nixpkgs/pull/189318#discussion_r961764451
also adds an activation script to print the warning during activation
instead of during build, otherwise folks using the new CLI that hides
build logs by default might never see the warning.
This commit fixes a papercut in nixos-rebuild where people wanting to
switch to a specialisation (or test one) were forced to manually figure
out the specialisation's path and run its activation script - since now,
there's a dedicated option to do just that.
This is a backwards-compatible change which doesn't affect the existing
behavior, which - to be fair - might still be considered sus by some
people, the painful scenario here being:
- you boot into specialisation `foo`,
- you run `nixos-rebuild switch`,
- whoops, you're no longer at specialisation `foo`, but you're rather
brought back to the base system.
(it's especially painful for cases where specialisation is used to load
extra drivers, e.g. Nvidia, since then launching `nixos-rebuild switch`,
while forgetting that you're inside a specialisation, can cause some
parts of your system to get accidentally unloaded.)
I've tried to mitigate that by improving specialisations so that they
create a dedicated file somewhere in `/run/current-system` containing
the specialisation's name (which `nixos-rebuild` could then use as the
default value for `--specialisation`), but I haven't been able to come
up with anything working (plus it would be a breaking change then).
