>Description:

Consider:

$ sudo rndctl -l|grep -i d0
sd0                 1068542 disk 
cd0                       0 disk 

Try to enable mutliple devices at the same time:
$ sudo rndctl -ce -d cd0 sd0

List afterwards:
$ sudo rndctl -l|grep -i d0
sd0                 1068542 disk 
cd0                       0 disk estimate, collect

Same thing with -t:
$ sudo rndctl -ce -t disk net

$ echo $?
0
$ sudo rndctl -l

>How-To-Repeat:
Begin working on /etc/rc.d/rndctl; become frustrated by the silent failure
>Fix:
I'm checking the code in the AM.  Something with argv[] processing.
