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.
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"
];
```
The MemoryDenyWriteExecute systemd option is widely known to be
incompatible with nodejs, and causes service crashes as reported in #119687.
Fixes#119687.
Adds the ability to provide the --write flag in addition to the --serve flag via
a new option, services.sshServe.write.
A user can now share their system as a remote builder with friends easily as
follows:
{
nix = {
sshServe = {
enable = true;
write = true;
keys = ["ssh-dss AAAAB3NzaC1k... alice@example.org"];
};
};
}

Matrix homeservers have two important domains. The user-visible server_name and the homeserver domain which serves most of the traffic but is really seen by users. The docs around this variable said "This is used by remote servers to connect to this server" which is very confusing because most of the remote server traffic actually goes the server domain, not the server_name domain. (The server_name domain is only used to fetch the .well-known file that points at the server domain).
I largely copied the wording from https://matrix-org.github.io/synapse/latest/usage/configuration/homeserver_sample_config.html as I found it much more clear.
