By scanning for LUN 0 only, we may encounter a device that the

Seems reasonable and applies clean to my development true. For
rescan-scsi-bus.sh I usually defer to Hannes. I have put it in
pending a decision from him.
BTW My alphas and betas (and releases) of sg3_utils go out through
Hannes' github account [https://github.com/hreinecke/sg3_utils] and/or
http://sg.danny.cz/sg . At the moment the latter is more up to date.
