FreeBSD is in the process of switching from nvd(4) to nda(4) as the disk device front-end to NVMe. Changing the default in the kernel is tricky since existing systems may have /dev/nvd* hard-coded e.g. in /etc/fstab; however, there's no reason to not change the default in HEAD for *new* systems. At present I have no intention of MFCing this to stable branches, since someone might reasonably expect scripts they use for launching and configuring FreeBSD 12.1 instances to work with FreeBSD 12.2 AMIs, for example. Reviewed by: gjb, imp Relnotes: NVMe disks in EC2 instances launched from 13.0 and later now show up as nda(4) devices.
