As far as I know, dnf-automatic is a replacement for "dnf upgrade" that
is more suitable for use in a script.

95% of the time "dnf --refresh -y upgrade" won't cause issues, but it's
that 5% of the time where it DOES screw up that will drive you barking
mad. Microsoft has had some absolutely horrific problems doing this
"upgrade on shutdown" behind the scenes crud and THEY have utter control
of ALL the software being upgraded during the process. That's not
necessarily the case with any community-supported system with multiple
repositories such as Fedora.

I'm just saying that "here be dragons." Thou hast been warned and may
proceed at thy own risk! :-)
