# Fact: operatingsystemrelease
#
# Purpose: Returns the release of the operating system.
#
# Resolution:
#   Uses the release key of the os structured hash, which itself
#   operates on the following conditions:
#
#   On RedHat derivatives, returns their `/etc/<variant>-release` file.
#   On Debian, returns `/etc/debian_version`.
#   On Ubuntu, parses `/etc/lsb-release` for the release version.
#   On Suse, derivatives, parses `/etc/SuSE-release` for a selection of version
#   information.
#   On Slackware, parses `/etc/slackware-version`.
#   On Amazon Linux, returns the `lsbdistrelease` value.
#   On Mageia, parses `/etc/mageia-release` for the release version.
#
#   On all remaining systems, returns the kernelrelease fact's value.
#
# Caveats:
