And this morning’s lessons are…

  • If you’re about to start something dangerous (like an aptitude upgrade on your dom0), and you set up an at job to reboot it if it causes the box to lose network connectivity, don’t forget to atrm it if everything is fine afterwards.
  • reboot in an at job doesn’t do the right thing – my box was still responding to pings but I couldn’t get to it at all. Next time try shutdown -r now
