It should appear right away if we attach sysfs stuff prior to the devices
which probe asynchronously.
Yes, it does appear pretty early, 
I thought scsi_debug had generic sysfs files to control adding new scsi devices
at run time or removing them, or controlling the scsi_debug driver generically,
but correct me if I'm wrong, I don't see them. If so then my statement was
incorrect in that "should" is an assumption.

All the sysfs knobs I'm seeing are per scsi device, not generic. And so I take
it back. Since scsi probes asynchronously its by chance they appear by the time
modprobe completes.
