Ask HN: Unattended Updates on CentOS/EL 7/8 ?

Anyone using the builtin Red Hat unattended updates (via yum-cron I believe) at scale at their workplace on CentOS 7 and or Rocky/Alma 8 ? My main question is, is it stable with small percentage of surprises/caveats/gotchas? And secondary question is— what is your strategy for related reboots? Do you script some sort of corollary logic to do reboots perhaps in certain dates/windows, etc? Or do you handle the reboot logic via Spacewalk or some other tool? If the unattended updates kind of mostly just work, think the reboot logic strategy/process/workflow will be the main pain point for scaling it out over a large number of servers that will need various different reboot windows, and within that window (say a 6 hr window), I’d like to have a random reboot within that window etc…. Obviously there is commercial software for this, but I’d like to keep it open source if at all possible.. Thanks for any feedback!
