AVC from smartd

[Paul Howarth <paul city-fan org>]

One of the drives in my RAID1 array failed this evening, so smartd let
me know about it by email. Along the way, it generated an AVC (F8):

type=AVC msg=audit(1201808872.737:2426): avc:  denied  { read } for
pid=27830 comm="sh" name="urandom" dev=tmpfs ino=2374

egid=0 sgid=0 fsgid=0 tty=(none) comm="sh" exe="/bin/bash"
subj=system_u:system_r:fsdaemon_t:s0 key=(null)

Not quite sure why it needed to access /dev/urandom, and it doesn't
appear to have stopped the mail being sent, so maybe this is one to be
dontaudit-ed?

Paul.
