Uh? The kernel sources are available to you. You check them out, see wether they are secure or not, and decide.

Bad move. You should have used /dev/urandom.

/dev/random does NOT fall back into pseudo random number mode. /dev/urandom does. Sorry to have to tell you, but you should have RTFM first.
