I agree with you in principal Warner, but it's not at all clear that the
real problem is srandomdev(). For instance, I just took a look at my laptop
and noticed that there was still an old version of the fortunes2 file in
/usr/share/games/fortune. The first fortune in that file is the one that I
have been seeing with much greater frequency than the others, so I deleted
those old files and we'll see what happens from here.
I also changed my fortune invocation in my shell startup file to:
/usr/games/fortune -D -D -D -sa 2>$HOME/fortune-debug
sysctl kern.random.sys.seeded >> $HOME/fortune-debug
Hopefully that will tell us something interesting.
Doug
