Overview ¶
Package state persists the bits of agent identity that have to survive across runs: the machine UUID (when /etc/machine-id is unavailable) and the monotonic scan sequence counter.
The token credential is NOT here; it lives at /etc/ghostpsy/agent.conf (see internal/agentconfig). State is read/written by every scan and is kept under /var/lib/ghostpsy/ because the agent runs as root via cron or systemd; per-user XDG locations would land in /root/.config which is not a sensible home for system-service state.

Functions ¶
func MachineUUIDFromOS ¶
MachineUUIDFromOS returns a UUID derived from the host D-Bus/machine ID when available.
We do not use github.com/shirou/gopsutil/v4/host.HostID (see host_linux.go): that API tries /sys/class/dmi/id/product_uuid first, then /etc/machine-id, then /proc/sys/kernel/random/boot_id. For Ghostpsy we need (1) stable OS identity from /etc/machine-id (e.g. Docker audit entrypoint may seed it), not DMI product UUID, and (2) never boot_id, which changes every reboot and would create a new machine row after each boot. Linux writes 32 lowercase hex bytes to /etc/machine-id (or /var/lib/dbus/machine-id). The value is formatted as a standard UUID string for ingest (backend stores uuid.UUID).
func Save ¶
func Save(s *AgentState) error
Save writes the state file with mode 0600 owner=root and creates the containing directory if missing.
Types ¶
type AgentState ¶
AgentState is persisted after the first successful scan: a stable machine identity and the scan_seq counter.
func Load ¶
func Load() (*AgentState, error)
Load reads the state file. Returns an error when the file is missing, malformed, or has no machine UUID.
