There is a hint of what some of the settings do in earlier posts.
The set common args seems pretty self explanatory that it is setting flags for the ds3617 on boot. A 0 representing a negative value of false and a 1 representing a positive value of true.
The options themselves come down from the Linux Kernel Boot Parameters, and there are too many to name in one post. You can browse common ones here.
Hope that at least points you in a helping direction?
I think somebody already did something similar with php scripts on the Synology forums over here.
Maybe it could be modified and used to benefit your particular problem?
