I would say that in these days, re-burials, without fanfare, could be done in an Ossuary Box. A wooden container just long enough to take the longest bone (as previously mentioned). It is expected that most discoveries these days would be skeletal.
Now, if you go to a well attended re-burial, you would watch what happens with the coffin. If the coffin is lowered into the grave and the "lowering ropes/straps" are removed, then I would form the opinion that it is going to stay there. But, if the ropes/straps are still in place, or if the coffin is supported at ground level and people are encouraged to depart, then, I suppose, you have room to wonder about whether it is staying or not.
For me, as long as it is done reverently, I have no problems with an Ossuary Box.
To clarify the condition of the remains discovered at Fromelles. Not sure about a previous suggestion that there may have been quantities of biological matter on the bones discovered there but I was present when Dr Tony Pollard said that the "skeletal remains" were in excellent condition and that DNA testing success was without a doubt. Now, admit that I am not fully informed, but that is what he said when the remains were first revealed.
The next point is that the 250 sets of remains were stored within the portable buildings that were there, on site...they would take a lot of room if they were kept in a fully supine position.
