feat: capture early-boot logs to a configurable path - #13
Merged
Conversation
Buffer early-boot stdout/stderr in RAM with byte and line limits, tee raw bytes to the console, and flush to earlyBoot.logsPath after the script exits so NVMe /data migration still lands on the final mount. Harden the reader against invalid UTF-8 and unterminated lines, fsync the log file, record terminating signals in the header, and best-effort persist on fatal early-boot via --early-boot-logs-path or an existing config peek.
