Yes theres a bug in dracut. hhoyer said it would be fixed in an update soon. Heres how to fix it:

commit 769cf2477076a0ec0ab40de329eddc6d33435dde
Author: Dominick Grift <domg472 at gmail.com> 2010-05-14 18:26:02
Committer: Dominick Grift <domg472 at gmail.com> 2010-05-14 18:26:02
Parent: 05997000a2389e510dd924bcf37b61c93b09f83a (Remove unused comments.)
Child:  f68796e9a8fd8c5234faf06484c99f2028c7b652 (Version 3.7.19-16.3)

Added this:
                mount --bind /dev "$NEWROOT/dev"
                chroot "$NEWROOT" /sbin/restorecon -R /dev
to:
/usr/share/dracut/modules.d/99base/selinux-loadpolicy.sh
so that devtmpfs gets restored right after dracut loads policy.
So now we should be able to remove:
dev_rw_generic_chr_files for both init_t and initrc_t i guess.
instead add dev_read_urand(init_t)
