SD only is not something I tried, but you can use the various 
--enable-build-DAEMON options to ./configure.

On the machine where you build it.

No.

There's a chapter in the manual covering this...

Why not? bscan does exist, and you should really have a database dump

Again - why not? Obviously, the machines and OSes need to be similar, 
and you need the required hardware, but apart from that, no problem 
(installation from binary package doesn't do much else, actually...)

Then you should read more of the manual :-)
