[CentOS-devel] CentOS 8 on AWS

Hi David,

io_timeout for nvme is in that gist. It's a uint 7.5 onwards.

Not clear on the second part. Are you saying there are patches in RHEL AMIs
that don't exist RHEL 8.2 and therefore aren't in CentOS 8.2? Or are you
just pointing out that since there are no CentOS 8.2 AMIs there is some
aarch64 support lagging. That's an important distinction.
