I have 2.0 kernel and /dev/random and /dev/urandom both exist.
It seems that the 'if' code is never getting executed due to the
'-f' option check... /dev/random and /dev/urandom will never be
plain files, right? I changed this to '-e' to check for existence
instead. Is that what was intended? Thanks!
