I don't need write permission, just read (cdparanoia to to produce .wav).

CDs are removeable and don't contain system files, private user's files,

Can I treat the absense of suid bit of cdparanoia executable and

Of course, I can, is it processed correctly by
./build.sh install, /usr/sbin/postinstall, etc.?
