Otherwise liquidd startup fails. This bug was not covered by our tests,
because we're not combining `regtest` with `secure-node`.
But nixbitcoin.org does, which should suffice for now.
This allows whitelisting local services without implicitly
whitelisting all inbound onion connections, which would happen when
setting bitcoind/liquidd option `whitelist=localhost`.
Used by electrs and nbxplorer, which requires the unsafe `mempool`
permission.
Benefits of adding top-level variables for used services:
- Makes it obvious which other services are referenced by a service
- Less code
We already do this in many other places.
These are insignificant, generic options; place them above readonly options.
We already do this in other services.
Also move user/group config to bottom in spark-wallet.
This greatly improves readability and makes it easier to discover options.
This commit was genereated by running the following script inside the
repo root dir:
#!/usr/bin/env ruby
def transform(src)
return false if src.include?('inherit options;')
success = false
options = nil
src.sub!(/^ options.*?^ }.*?;/m) do |match|
options = match
" inherit options;"
end
return false if !options
src.sub!(/^with lib;\s*let\n+/m) do |match|
success = true
<<~EOF
with lib;
let
#{options}
EOF
end
success
end
Dir['modules/**/*.nix'].each do |f|
src = File.read(f)
if transform(src)
puts "Changed file #{f}"
File.write(f, src)
end
end
`generate-secrets` is no longer a monolithic script. Instead, it's
composed of the values of option `nix-bitcoin.generateSecretsCmds`.
This has the following advantages:
- generate-secrets is now extensible by users
- Only secrets of enabled services are generated
- RPC IPs in the `lnd` and `loop` certs are no longer hardcoded.
Secrets are no longer automatically generated when entering nix-shell.
Instead, they are generated before deployment (via `krops-deploy`)
because secrets generation is now dependant on the node configuration.
Now that service uid, gid mappings are included in the backups, along
with the service data dirs, we can remove 'chown -R' for
clightning and liquidd data dirs.
Note that we used 'chown -R' only for these two services, while this
approach would have been relevant for all services with data dirs.
Systemd's `Description` option is a misnomer (as confessed by `man systemd.unit`):
Its value is used by user-facing tools in place of the unit file name, so this option
could have been more aptly named `label` or `name`.
`Description` should only be set if the unit file name is not sufficient for naming a unit.
This is not the case for our services, except for `systemd.services.nb-netns-bridge`
whose description has been kept.
As an example how this affects users, weird journal lines like
```
nb-test systemd[1]: Starting Run clightningd...
```
are now replaced by
```
nb-test systemd[1]: Starting clightning.service...
```
- Remove redundant option mainchainrpchost.
This option is already provided by bitcoind.
- Set a working default for rpcport and rpcuser.
Enables use without secure-node.
- Adds liquidd to netns-isolation.services
- Adds rpcbind, rpcallowip, and mainchainrpchost options to allow using
liquidd with network namespaces
- Adds bind option (defaults to localhost) as target of hidden service

This is NixOS' recommended way to setup service dirs
https://github.com/NixOS/nixpkgs/pull/56265. This commit hands off the
initial data directory creation to systemd.tmpfiles.rules. All other
preStart scripts are left intact to limit this changes' scope.
