Option `services.lnd.restOnionService.package` has been removed.
There's not much use in overriding the [lndconnect pkg](https://github.com/LN-Zap/lndconnect).
- Rename `services.rtl.cl-rest` to `services.clightning-rest`.
`clightning-rest` is generally useful for connecting external REST clients
to clightning.
- Add a dedicated network namespace in netns-isolation.
- Add nodeinfo entry.
- Add datadir (which contains REST auth data) to backups.
- enable usage outside of secure-node.nix
- use json as the output format
- show ports
- also show local addresses, which is particularly useful when
netns-isolation is enabled
- only show enabled services
Mitigates a security issue that allows unprivileged users to read other
unprivileged user's processes' credentials from CGroup using `systemctl
status`.
- Adds network namespace instantiation and routing architecture.
- netns-isolation disabled by default. Can be enabled with
configuration.nix FIXME.
- Uses mkMerge to toggle certain options for non netns and netns
systems.
- Adds security wrapper for netns-exec which allows operator to exec
with cap_sys_admin
- User can select the 169.254.N.0/24 addressblock netns's are created in.
- nix-bitcoin-services IpAddressAllow is amended with link-local
addresses
Add ProtectSystem=strict, remove PermissionStartOnly.
Extract the section of postStart that needs secrets dir write
access into a separate script with full privileges.
Simplify preStart and fix dataDir quoting.
currently, nodeinfo has presets/secure-node.nix as a strict
dependency as it requires onion-chef and the 'operatorName' option.
and nix-bitcoin-webindex.nix has nodeinfo as a dependecy.
so don't add nodeinfo and webindex to modules.nix because they will fail on standalone use.
Each secret file to be deployed is now backed by one local file.
This simplifies 'setup-secrets' and the secret definitions.
Also, with the old format it was not possible to add new secrets
to secrets.nix in a simple way.
Old secrets are automatically converted to the new format when running
nix-shell.
Using the new option 'nix-bitcoin.secrets', secrets are now directly
defined by the services that use them.
Not polluting the main pkgs namespace with internal pkgs makes it
easier to integrate the nix-bitcoin modules into a larger config.
Also, by overriding the nix-bitcoin namespace, users can now easily set the
packages used by services that offer no explicit `package` option, like `clightning`.
