Where is nfsiod now?

[Yoshihiro Ota]

Hello.

I thought rc used to start nfsiod if you set nfs_cilent_enable
back years ago.
Now, on my 7.1-RELEASE machine, it sets up a couple of sysctls
in /etc/rc.d/nfsclient script but not nfsiod.

Is nfsiod obsolete by now?
It is still on the system; does it still improve nfs performance?

Thanks,
Hiro
