Root cause of the fresh-install triple failure (LND needing ~5 install
attempts, Bitcoin UI bitcoin-rpc 502, backend getblockchaininfo errors):
the legacy conf writer set rpcallowip but never rpcbind, so bitcoind
bound RPC to the container's loopback only — every dial over the
container network (LND, bitcoin-ui) and the rootless port-forward was
refused. LND exited instantly, the 60s post-start poll read that as
INSTALL CRASH, and the wallet (and its seed backup) never got created.
- write_bitcoin_conf + ensure_bitcoin_rpc_config now emit/ensure
rpcbind=0.0.0.0 (host exposure unchanged: publish stays 127.0.0.1)
- new install gate: bitcoin-dependent apps (lnd/electrs/electrumx/
mempool-electrs/btcpay) wait up to 3 min for an authenticated
getblockchaininfo to answer before their container starts, with
INSTALL WAIT progress lines; on timeout the install fails with an
actionable message instead of a crash-looping container
Verified live on the fresh-ISO framework node: after adding rpcbind and
restarting bitcoin-knots, LND connected, created its wallet, baked
macaroons, and settled into 'Waiting for chain backend to finish sync'.
