Do you need to get root involved? If a hacker can substitute his
reboot_notify for yours, he gets full control.
Being such a beginner, I didn't realize I was creating a problem with root...I
took your advice and removed "sudo"...is that enough, or is there something
else I should do for security?
Hello Jon, Any script in rc.local is probably called by root, so it's best to
follow the example of NUT itself and drop to a non-privileged with something
like
sudo -u nut /usr/local/bin/reboot_notify
This list is relaxed about top posting versus bottom posting, but as you venture
futher into the Linux world, you will meet lists which expect bottom posting, so
it's helpful to get into the habit.
