Hello all, before I upgrade the Tailscale plugin I open a terminal window and issue a command to reboot the server a little bit in the future like this:

echo "powerdown -r" | at 14:05

This has saved me a few times in the past when the Tailscale update went sideways and lost access to a remote server. The scheduled reboot would restore access. Recently, I have noticed the at job is removed and the terminal window is closed during the Tailscale update. Before it does this it creates another job as shown using atq.

How can I prevent the Tailscale update from removing "my" at job or how can I schedule a reboot without at ?

Run it in a tmux session, or add & at the end to detach it from the terminal?

Thank you for your reply!
I did use tmux. I have the TMM plugin installed and used that. The update closed the window and apparently killed the tmux session - there were no running sessions when I clicked on TMM again. Also, I am past the point where the at command would have rebooted the remote server and it did not reboot.
