needrestart - Raspberry Pi

Raspbian and other linux distros are installing multiple kernel images in parallel:

• kernel.img
• kernel7.img
• kernel7l.img
• kernel8.img

This might result in a continuous pending kernel update false positive. There is a configuration option in needrestart to filter the kernel image filenames to ignore the unused image files. To filter the kernel image on a RPi 2 or RPi 3:

$ cat << EOF > /etc/needrestart/conf.d/kernel.conf
# Filter kernel image filenames by regex. This is required on Raspian having
# multiple kernel image variants installed in parallel.
$nrconf{kernelfilter} = qr(kernel7\.img);
EOF
