I think all real SCSI hardware I've had has always just only had LUN 0,
and each disk has been on its own SCSI ID (target).

Well, this is how Proxmox and Linode do it, and with this change it is
possible to install and use NetBSD on those platforms.

Of course, anyone running their own Proxmox could just avoid the "Virtio
SCSI single" controller type (or SCSI disks altogether), but there is
no user or admin control for specifying the LUN ID of a disk.

With a platform like Linode, you are stuck with the configuration it
creates for you from a boot profile (or other UI object). Although Linode
is usually responsive to bug reports, here it is not clear if the bug is
in how they do things or how NetBSD behaves.

With this change it is possible to run the NetBSD installer just like
the FreeBSD one (or any other "custom distro") on Linode.

Kind regards,
