Don't worry, it's is true by default. But I think this is important to
have because NixOS indeed shouldn't need Nix at run time when the
installation is not being modified, and now we can verify that.
NixOS images that cannot "self-modify" are a legitamate
use-case that this supports more minimally. One should be able to e.g. do a
sshfs mount and use `nixos-install` to modify them remotely, or just
discard them and build fresh ones if they are run VMs or something.
The next step would be to make generations optional, allowing just
baking `/etc` and friends rather than using activation scripts. But
that's more involved so I'm leaving it out.
I realized quite recently that running a test VM - as documented in the
manual - like
QEMU_NET_OPTS='hostfwd=tcp::8080-:80' ./result/bin/nixos-run-vms
doesn't work anymore on `master`. After bisecting I realized that the
introduction of a forward-port option[1] is the problem since it adds a
trailing comma even if no forwarding options are specified via
`virtualisation.forwardPorts`. In that case, the networking options
would look like `-netdev user,id=user.0,,hostfwd=tcp::8080-:80' which
confused QEMU and thus the VM refused to start.
Now, the trailing comma is only added if additional port forwards are
specified declaratively.

NixOS should be able to support the Nintendo Switch Pro controller for
steam and non-steam at the same time. Currently there are two mutually
exclusive ways to support the Pro Controller: Steam and `hid-nintendo`.
Unfortunately these don't work together, but there's a workaround in
newer versions of `joycond` (described [here](https://wiki.archlinux.org/title/Gamepad#Using_hid-nintendo_pro_controller_with_Steam_Games_(with_joycond))). To use this
workaround `hid-nintendo` and `joycond` need to be updated, and the
systemd and udev configuration needs to be made available in NixOS.
We have no usecase for manually/selectively starting or stopping VLANs
in integration tests.
By starting and stopping the VLANs with the constructor and destructor
of VLAN objects, we remove the obligation and complexity to maintain
network lifetime separately.
This commit encapsulates the involved domain into classes and
defines explicit and typed arguments where untyped dicts where used.
It preserves backwards compatibility through legacy wrappers.
* less: enable by default and set LESS=-R via lesskey
* since we set PAGER=less, programs.less.enable should default to
true.
* some programs, notably git, set a custom LESS environment if none is
present. using the lesskey mechanism to set LESS=-R lets such
programs continue to run less as they see fit.
This reverts commit 0e7b4e60a846af1d4487ebe1218f8e07fffaa89b.
* less: remove use of deprecated lesskey binary format
* less: enable in environment.nix rather than less.nix

This module allows setting global configuration for htop in /etc/htoprc,
for example to disable showing userland threads by default

This is the first version of the mautrix-facebook module. Due to lack of secret support on NixOS as well as the requirement of a homeserver domain it requires some setup. For completeness here is my working config using NixOps secrets:
```nix
deployment.keys."mautrix-facebook-config.env" = {
text = ''
MAUTRIX_FACEBOOK_APPSERVICE_AS_TOKEN=${secrets.as_token}
MAUTRIX_FACEBOOK_APPSERVICE_HS_TOKEN=${secrets.hs_token}
'';
destDir = "/var/keys";
};
deployment.keys."mautrix-facebook-registration.yaml" = {
text = builtins.toJSON config.services.mautrix-facebook.registrationData;
destDir = "/var/keys";
user = "matrix-synapse";
};
users.users.matrix-synapse.extraGroups = ["keys"];
systemd.services.matrix-synapse.after = ["keys.service"];
systemd.services.matrix-synapse.wants = ["keys.service"];
services.mautrix-facebook = {
enable = true;
settings = {
homeserver.domain = "bots.kevincox.ca";
bridge = {
displayname_template = "{displayname}";
permissions = {
"@kevincox:matrix.org" = "admin";
};
};
};
environmentFile = "/var/keys/mautrix-facebook-config.env";
registrationData = {
as_token = secrets.as_token;
hs_token = secrets.hs_token;
};
};
systemd.services.mautrix-facebook = rec {
wants = ["keys.target"];
after = wants;
};
services.matrix-synapse.app_service_config_files = [
"/var/keys/mautrix-facebook-registration.yaml"
];
```
