1. Parse os-release to identify OS by ID_LIKE field …

   The /etc/os-release file has evolved over the years, with current
   documentation being at
   https://www.freedesktop.org/software/systemd/man/latest/os-release.html
   
   Part of this spec is to also look at /usr/lib/os-release as image based
   Linux distributions that can exist without anything in /etc may put the
   os-release file there.
   
   In the docs, Example 3 shows how to parse this file with shell. We can
   use that example and look at ID_LIKE to better determine if the OS is a
   Debian like system, or a Fedora like system, and differentiate between
   how RHEL / CentOS and friends are like Fedora and how non-RHEL,
   non-CentOS is also like Fedora.
   
   The practical end-outcome of this is that it will now correctly detect
   Amazon Linux 2023, pick 'dnf' as the package manager, and install the
   dependencies.
