Module stop_record 

The last stop, kept where it survives the stop (2026-10-01, the real test2 run 9: vm1 stopped cleanly, but its power-off steps were lost — the narration and the disk log die with the read-only remount of /data — and UpCloud reported stopped 46 s after the soft stop, so nobody could tell the guest’s power-off from the provider’s reporting). After the quiesce and just before the power goes, ONE line is written on the ESP (its own filesystem, flipped read-write for that write); the next boot says it at INFO and removes it.

Constants

RECORD

Where the record lives on the ESP.

SAID

The words the next boot says the record in — what the installer’s kit looks for.

Functions

keep

Write the record for a stop said as line, stamped now — the last write before the power.

power_off_epoch_ms

The power-off time out of a record (or out of the line the next boot said it in).

render

The record: power_off_epoch_ms=<ms> <the stop's line> — one line, no newline in it.

say_previous

At boot: say the previous stop’s record (if any) at INFO, then remove it.
