#!/usr/bin/env bash
# A script to upgrade a RHEL derivative (Fedora, CentOS, ...). If you have ansible or puppet:
# this is way more simple with an automation framework. This script works with the paradigm
# that you only have a bash available and you want to see what happens without being murdered
# by gazillions of output lines.
# This script avoids combining options, e.g. dnf -C -q instead of dnf -Cq, since
# dnf is perfectly capable of POSIX standards, but yum fails at combined parameters.
# So we'll leave it this way in case of conversion of this script to yum or extension
# to be capable of both. (tl;dr no combined options because yum sucks at POSIX standards)
# LOGGING UNIT
# We are not ignoring logging frameworks like many software out there. We'll be using logger(1) to
# log what we are doing, and it's up to you to redirect it to a specific file if you need to.
# Define the name of the logging unit/tag here:
LOGUNIT="dnfu"
# DETAILED LOG
# To not spam the logging centre with all of our debug, we will create a temporary file nonetheless.
# The script will log its destination in the end, so we can make use of mktemp(1) here.
