@Myst - The installation script from the GitHub repository uses pm2 to start Magic Mirror. The pm2 application starts and monitors a script in the /home/pi/MagicMirror folder named run-start.sh. If the script crashes/exits for any reason, pm2 will detect it and restart that script.

As with every update, even from big companies like Microsoft, there is always a risk of breaking something

@Myst yes, would make sense in the wiki
