Bug#874085: smartmontools: [smartd.conf] UNRECOGNIZED OPTION: U

[Christian Franke]

There is no smartd command line option -U (see 'smartd -h' or 'man 
smartd') but a smartd.conf directive -U (see 'smartd -D' or 'man 
smartd.conf').

Conclusion: Place '-U 198+' in the file /etc/smartd.conf instead.
