anti
215251a122
decnet-bus.service.j2 ran with User={{ user }} / Group={{ group }}
but the actual bus CLI invocation hardcoded --group decnet. The bus
chowns /run/decnet/bus.sock to that group at 0660 — so when an
operator ran `decnet init --group anti`, the socket ended up
owned by decnet:decnet while every worker (agent, api, collector,
forwarder, prober, updater) ran as anti and got EACCES on connect().
Each worker's bus-wiring catches the error, logs a warning, sets
bus=None, and carries on — which is correct for the data-plane but
silently kills Workers-panel heartbeats (run_health_heartbeat(None,
...) no-ops). So half the worker grid showed UNKNOWN even though
systemctl confirmed the processes were alive.
Swap the hardcoded --group decnet for --group {{ group }} so the
socket is owned by the same group the workers run under.

# /run/decnet is created automatically with the RuntimeDirectory= directive
|
|
# below (mode 0755, owned by User/Group) and cleaned up on stop. The bus
|
|
# socket is placed inside it with 0660 perms so only the configured
|
|
# DECNET group (--group) can connect. That group is rendered here so
|
|
# `decnet init --group anti` results in a socket every worker running
|
|
# as anti can actually connect() to — otherwise every worker falls
|
|
# back to bus=None and the Workers panel sees no heartbeats.
