Further messages indicated that some updates were being installed. After some 
minutes the system rebooted.

Everything known has been done to prevent any automatic updates with manual dnf 
being used as needed. The pam_login module looks for the existence of

/etc/nologin or

/var/run/nolongin

What is updating files without a command  and writing these entries?
You mentioned you disabled DNF auto updates, but is the 
packagekit-offline-updates.service unit running?  That can also perform updates 
(via PackageKit->dnf) and reboot.  Perhaps the login shell was somehow added to 
the system-update.target?

It’s worth looking at the journal at that time to see what was running.  This 
isn’t a completely unsolvable mystery, all the actions will be in the journal.
