Check if system needs reboot

Difficulty: ★★☆☆☆

Description

Some system updates will require you to restart your system. Packages includes microcode, kernel, driver, xorg and systemd as likely candidates. Below is a list of packages which may warrent a system restart. If you can think of other packages to include in the check just add the package(s) to the $reboot regex in the script.

ucode
cryptsetup
linux
nvidia
mesa
systemd
wayland
xf86-video
xorg

Utility script

The script calls the checkupdates script - and yay if installed - and uses regular expression to suggest a possible system restart.

#!/usr/bin/env bash
reboot="(ucode|cryptsetup|linux|nvidia|mesa|systemd|wayland|xf86-video|xorg)"
if [[ $(which yay) =~ (yay) ]]; then
    updates=$(checkupdates; yay -Qua)
else
    updates=$(checkupdates)
fi
echo "$updates"
if [[ $updates =~ $reboot ]]; then
    echo "Updating possibly requires system restart ..."
fi

Usage

As noted in comments the check is very broad and not intended by any means to be authoritative - it only serves the purpose of suggesting - before updates are installed - if system restart could be necessary.
