Line 21: different option values in the tuple list which are now mandatory
Line 22: to have some constant/'already defined' value.
Line 23: ex:- changelv(vg, lvs, ('-autobackup', 'y'))
> I'm not sure what do you mean here - is there a conflict between the new op
Yes, currently its not possible to call this function with autoback true.

For ex:-
Currently this function adds ( "--autobackup", "n") argument to lvchange.
[line no: 805 cmd.extend(LVM_NOBACKUP)]
If someone calls with ('autobackup', 'y'), the lvchange command will have two 
different options for autoback one is set to false and another sets to true.
ex: lvchange --autobackup n --autobackup y ...
