Probably nothing. I have reason to believe that at least 50 people for whom I have done installs have never logged in to their server.
Well, you do want to do the OS upgrades, but you can set it up so that you don’t have to think about them.
I don’t (currently) automate doing a
./launcher cleanup, but you can automate a bit more of the Ubuntu stuff with
dpkg-reconfigure -phigh unattended-upgrades
echo 'Unattended-Upgrade::Remove-Unused-Dependencies "true";' >> /etc/apt/apt.conf.d/50unattended-upgrades
echo 'Unattended-Upgrade::Automatic-Reboot "true";' >> /etc/apt/apt.conf.d/50unattended-upgrades
echo 'Unattended-Upgrade::Automatic-Reboot-Time "09:00";' >> /etc/apt/apt.conf.d/50unattended-upgrades
Best I can tell, the difference between
-plow is that the former doesn’t ask you any questions.
If you’re someone who’s not likely to log in to your server, you really need to reboot it without your having to log in if security updates require a reboot. The time is in UDT, 9:00 is 5AM EST and 2AM PST (and I guess it might be an hour different from that now). A reboot takes just a minute or two. The 40 or so people for whom I left the reboot time at 2:00, haven’t complained.
If you want an occasional sysadmin to intervene in some emergency or do a check-up, or want someone to pay attention to upgrades and such I am available as are others if you post in #marketplace.
