Here is something I have wondered about: If solaris assigns consistent device entries to a device that is hotplugged each time it is connected, which is certainly something that can be implemented, then how many such devices can it handle before it runs out of room for new devices? After all I could theoretically have 100000 usb and firewire cd-rw drives. What if I was to plug each one in one at a time in turn. Would it deal with that? What kind of references would I end up with for them by the time I hit number 99999? Do I end up with device 99999,0,0 in cdrecord/libscg? At some point you have to give up on old devices or you could end up having to keep an index the whole universe.
