I typically boot in mode 3 to a terminal. Fedora f39 going to lxde as the desktop. Today with a cold boot and entering the user login the following message showed

System is going down. Unprivileged users are not permitted to log in anymore , for technical details see pam_nologin(8)

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.
]# systemctl
status packagekit
○ packagekit.service - PackageKit Daemon
Loaded: loaded (/usr/lib/systemd/system/packagekit.service;
static)
Drop-In: /usr/lib/systemd/system/service.d
└─10-timeout-abort.conf
Active: inactive (dead)
~]# systemctl
status system-update.target
○ system-update.target - Offline System Update
Loaded: loaded (/usr/lib/systemd/system/system-update.target;
static)
Active: inactive (dead)
Neither of those commands are going to tell you what happened when you encountered the reboot. I don’t even know what to expect on running a systemctl status on a *target*.
You need to use journalctl to find the time in the journal leading up to the login and see what services were started. The “last” command should give you an idea of the timestamp.
