I suspect that the configuration key "init_fragment_count" is actually not configurable.
I mean, the user would never set it to anything other than 0.
Is there a place in the code where, if the key is not there, it can be inserted with the value of 0.
It's kind of a "hidden" or "non-user" or "system" key. I'm kind of surprised there isn't a better way to do this.
It's not that big of a deal, though -- could approve as is.

It is set by DAQInterface when it inspects the system configuration ("bookkeeping"). It needs to be set in the input configuration so that DAQInterface can update it to the correct value.

What happens if the user adds "init_fragment_count":1 or anything other than 0 (is there a wrong value)?
Is there any way to not increase the (configuration) demands on the user?

[eflumerf]

There is no wrong value. It just has to be in the input FHiCL document so that DAQInterface can overwrite it with the calculated value.
