Just fullyu updated yesterday. The reboot gets past CentOS (core)… and reboots. Repeatedly. messages *look* as though it got up… and then reboot.
Any clues?

Are you booting into graphical.target (gdm) or multi-user.target (text login)? Have you removed ‘rhgb quiet’ from the kernel parameters to see what it is doing? Can you boot into the rescue target and poke around in the journal to see what’s going on?
Since I.m traveling, I.ll do some when I get home…but as a sysadmin, I
*always* remove the rhgb quiet. Iknow it got past the base, and had gotten to welcome to:, Sometheing shortly after that, it reboots. Is there still the interactive option? If so, I can use that… thanks

No, there’s no longer an interactive option, since it’s no longer a linear boot.
Any chance that you’re seeing:
Welcome to emergency mode! After logging in, type “journalctl -xb”
I suspect that you’re dropping into emergency mode, but it is failing to launch the login prompt and rebooting. You could append ‘rd.break’
to the kernel command line in grub2 to make the initramfs break before trying to switch over to the boot OS, so you could poke around a bit more. The OS is in the /sysroot dir, you can chroot and run commands like rpm -V and journalctl to see if there’s any useful data.
