[Feature Request] Alert if action is needed after update (e.g. reboot)

[RudahXimenes]

Description

Sometimes when updating, we may need to reboot the system to apply the changes, for example when updating a kernel. So I thought about create a script to check if there is any crucial update that needs to reboot and then show in tray. Then I asked myself: why not suggest to the Arch Linux Update Indicator to include it, as long as I don't know how to deal with extensions and stuff? So here I am.

Script

I found a script in internet to check kernel and libs, then I adapted to crucial updates (kernal, systemd, glibc and xorg). It depends on lsof, so it's a requirement

Here is the script

#!/bin/bash

get_boot_kernel() {
    local get_version=0
    for field in $(file /boot/vmlinuz*); do
        if [[ $get_version -eq 1 ]]; then
            echo $field
            return
        elif [[ $field == version ]]; then
            # the next field contains the version
            get_version=1
        fi
    done
}

rc=1

libs=$(lsof -n +c 0 | grep 'xorg\|libc\|systemd' | grep 'DEL.*lib' | awk '1 { print $1 ": " $NF }' | sort -u)
if [[ -n $libs ]]; then
    cat <<< $libs
    echo "# LIBS: reboot required"
    rc=0
else
    echo "# LIBS: No action needed"
fi

active_kernel=$(uname -r)
current_kernel=$(get_boot_kernel)
if [[ $active_kernel != $current_kernel ]]; then
    echo "$active_kernel < $current_kernel"
    echo "# KERNEL: reboot required"
    rc=0
else
    echo "# KERNEL: No action needed"
fi
exit $rc

Conclusion

Is it possible to add this feature to the extension?
It would be great!

Thank you!

I kinda like the idea, but I must find another way to do it. I don't want to add a dependency, and I cannot ship a shell script with the extension.
It must be done in javascript. I will try to see if what your script does can be achieved in JS. Hope so ;)
