The requirements are: (1) users must see the notice before logging in, (2) users must see the notice after logging in, and (3) currently logged-in users must be notified immediately. Select all actions that satisfy these requirements.

Edit /etc/issue to include the maintenance notice

wall 'Reboot in 10 minutes' && shutdown -r +10

shutdown -r 15:10 'Kernel update reboot'
