RE: How to add/drop SCSI drives from within the driver?

You are right, even though distributions (I checked Red Hat and SuSE) have
different /sbin/hotplug scripts (e.g., SuSE 9.2 will not execute files from
/etc/hotplug.d whereas Red Hat does) udev will be invoked in all cases,
which will take care of creating device nodes.

But our concern is that how would the applications get the cue that udev has
actually created the nodes for the new devices? 

Make sure an agent is called after the, e.g., scsi agents are executed from
/etc/hotplug directory (which happen to be scsi.agent, scsi_device.agent,
scsi_host.agent in one and only scsi.agent in other distribution), by
writing an rc like script?

Or more likely, by placing our agent in /etc/dev.d directory. Unfortunately,
there seems be not a consensus here as well. On system has "default" and
"net" directories and other has "block", "input", "net", "tty"?


Thanks
