Blacklist broken?

Title: Blacklist broken?

I just upgrade an FC13 system to FC15, and now multipath is grabbing the system drive before the normal fsck can run, which is causing the machine to not boot.  I get the message: “Filesystem mounted or opened exclusively by another program? “  Now, I can simply control-d to continue, but why is multipath grabbing the drive?  I’ve blacklisted it every way I can, using devnode, using wwid, it simply ignores it and continues to create a path map for /dev/sda.

device-mapper-1.02.63-3.fc15.x86_64
device-mapper-multipath-0.4.9-15.fc15.x86_64

[root@bonjovi ~]# blkid | grep boot

/dev/mapper/mpath0p1: LABEL="/boot" UUID="8ed92bb6-0ddb-4fbc-907d-fdf12e5550a3" TYPE="ext3" 

>From multipath.conf:

blacklist {
        wwid 36001ec90ee4ee600105ac65e04e84e61
        devnode "/dev/sda"
        devnode "/dev/sda1"
}
devnode_blacklist {
        wwid 36001ec90ee4ee600105ac65e04e84e61
        devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
        devnode "^hd[a-z]"
        devnode "^cciss!c[0-9]d[0-9]*"
        devnode “sda”
        devnode “/dev/sda”
}

I’ve even tried blacklisting by /disk/by/uuid.  What does it take to get multipath to quit grabbing this disk?
