Yes on both the Fedora and Debian boxes smartd is being run with the -s 
option:

/[root at gateway ~]# ps aux |grep smartd//
//root       10512  0.0  0.0  10640  6016 ?        Ss Mar27   0:00 
/usr/sbin/smartd -n -q never --interval=3600 -s /var/lib/smartmontools///
/

/root at debian:~# ps aux | grep smartd//
//root       466  0.0  0.0   7428  1448 ?        Ss   Mar15 0:01 
/usr/sbin/smartd -n -q never --interval=5400 -s /var/lib/smartmontools//

And on both of them the /var/lib/smartmontools folder has regularly 
updated .state files.

I tried that on the fedora box and it works just fine:

/[root at gateway ~]# smartctl -t select,cont 
/dev/disk/by-id/ata-ST6000VX001-2BD186_ZR13347M//

They both run 24/7 but we do have regular power outages here in South 
Africa - there has been none in the past two week though.

I also note that smartd is being run as root so should have permissions 
to run smartctl.
