I’ve been planning for some time to send a server to a datacenter to be free to announce my own IPs via BGP. The choice of OS running on this server is important, and I think that with Bootc + OSTree, I have a solution that suits me perfectly (because if I ever lock up the machine during an update, a simple reboot will restore it to a consistent state).
But there are plenty of wild cards ahead, as Ullrich and others are quick to acknowledge.

The primary signal is desiredSize on the controller. It can be positive (wants data), zero (at capacity), negative (over capacity), or null (closed). Producers are supposed to check this value and stop enqueueing when it's not positive. But there's nothing enforcing this: controller.enqueue() always succeeds, even when desiredSize is deeply negative.
