Description iwi 2002-07-09 12:27:37 EDT
From the "start" section of /etc/rc.d/init.d/random

        action $"Initializing random number generator: " /bin/true
        chmod 600 $random_seed
        dd if=/dev/urandom of=$random_seed count=1 bs=512 2>/dev/null

I could be mistaken, but it appears to me that the input and output of dd are
the wrong way round for this to actually feed any entropy into the random number

Closing this myself, as reporter.  This is not a bug.

I hadn't read the script carefully enough: it is a previous line that
initialises the random generator ("cat /var/tmp/random-seed >/dev/urandom").

Sorry to take your time.
