`cfg` is whatever the reading module bound it to. It does not exist in a
NixOS configuration, so a sentence naming an option as `cfg.<name>` is
correct about behaviour and unusable as an instruction — the reader has
to go find the real path.
The four sites in docs/networking/gateway.md this was filed for:
cfg.sshPort -> services.hyperhive.swarm.forge.sshPort
cfg.dashboardPort -> services.hyperhive.c0re.dashboardPort
cfg.frontend (x2) -> services.hyperhive.c0re.frontend
Sweeping docs/ for the pattern rather than the ticket's line numbers
found five more, in four other files:
approvals.md cfg.hyperhiveFlake -> services.hyperhive.c0re.hyperhiveFlake
matrix.md cfg.registrationTokenFile -> services.hyperhive.deploy.matrix.registrationTokenFile
matrix.md cfg.gatewayHost -> services.hyperhive.swarm.matrix.gatewayHost
conventions.md cfg.dashboardPort -> services.hyperhive.c0re.dashboardPort
gotchas.md cfg.dashboardPort -> services.hyperhive.c0re.dashboardPort
matrix.md is the clearest case for doing this at all: its two `cfg.`
references resolve to *different* option trees — `deploy.matrix` and
`swarm.matrix` — so the shorthand is ambiguous even within one file.
Each path is read off the `mkOption` that declares it plus the
`options.services.hyperhive.*` root it sits under, with the indentation
checked so a nested block cannot have been missed. `cfg.frontend` is
declared in hive-c0re, not the gateway: the gateway module binds
`cfg = config.services.hyperhive.gateway`, which has no `frontend`.
Deliberately unchanged: docs/networking/snapshot-store.md:136, where
`cfg.port` sits inside a ```nix block quoting module source. `cfg` is
correct there, and rewriting it would make the snippet wrong.
Closes#4193.
