LogGuard: System Crash Resilience

System logs often vanish after kernel panics or power failures, and oversized single‑line writes waste disk space and I/O. LogGuard delivers a WAL‑style, non‑volatile memory logging layer that guarantees durability across crashes and compresses large entries to keep write sizes efficient.

Comment on: Single log line is 49KB+ (ext4) / 110KB+ (btrfs) of systemd-journald disk writes

> complaints about logs being lost during a power failure or kernel panicI recall reading somewhere about a thing which persists data in a particular region of RAM that is guaranteed to be left alone by the kernel, and therefore will persist across a reboot. Buffering in such a region could persist data when the kernel panics but it obviously wouldn't survive loss of power.Wouldn't opening the file O_APPEND (maybe O_DIRECT also?) and using fdatasync be better? That way we've basically implemented a WAL and skipped all the other database parts we don't need or care about.
