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?
Maybe firmware updates -- these seem to differ depending on the type of device and vendor.
From https://en.wikipedia.org/wiki/Fwupd:
It [fwupd] is designed primarily for servicing the Unified Extensible https://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface Firmware Interface https://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel https://en.wikipedia.org/wiki/Linux_kernel 4.2 and later. [...] ESRT allows the firmware to expose updatable components to the operating system, which can pass a UEFI capsule with updated firmware for processing and installation on the next boot.
Journalctl may have more details, if you can find them amid the mass of detail journalctl provides. It would be nice to have a mechanism that highlights entries that are new to the current boot but have not appeared in previous boots.
