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! :-)

I whole hardheartedly agree with Rick on this point. That being

either first or where ever makes the most since. It has been awhile
since I messed with this but I think you need to research
manipulation of the rc.local directory files. Hope it helps, just a
pointer for you to look into.

I'm sure you could do something like that, but I'm absolutely not in
favor of unsupervised updates. There are times where updates can
result
in an unbootable system or various other issues. Error messages
would
not be visible during the upgrade, conflicts with packages from
other
sources might be missed, many other things might end up with a
system
that, even if it works, might behave rather differently than the
system
you shut down before.
You only have to look at the number of "bricked" Winblows system
upgrades that have occurred in the past using this scheme. No,
unsupervised or unobserved updates are a bad idea IMHO. I never
use "-y"
with dnf or pkcon or yum. I look at the proposed upgrades before
I ever
approve them--and there are MANY times I've rerun the command
with an
"--exclude=" so specific packages do NOT get upgraded.
You might disagree with much he did, but as Reagan said, "Trust, but
verify!"
