The Watchdog feature of the Raspberry Pi is both under-rated and under-publicised. As this website explains, Watchdog can be used to automatically restart your Raspberry Pi in the event of a system error that otherwise bricks the device. It takes <5 mins to install and enable Watchdog, and particularly for remote RPis, you could find it saves the day.

sudo -i
echo 'dtparam=watchdog=on' » /boot/config.txt
reboot

Then copy/paste these commands into your terminal, one at a time:

sudo -i
yes | apt install watchdog
echo 'watchdog-device = /dev/watchdog' » /etc/watchdog.conf
echo 'watchdog-timeout = 15' » /etc/watchdog.conf
echo 'max-load-1 = 24' » /etc/watchdog.conf
systemctl enable watchdog
systemctl start watchdog
systemctl status watchdog
