Good point.

Maybe a hybrid check which includes the /usr/share/misc/magic test
and a check for the existance of the segments could be used.

I dont know what segments are mandatory in a core file and it could
be a truncated file so maybe this is not a good idea.

Assuming the user knows what they are doing along with the magic
test should be enough.

"If it is true that our Universe has a zero net value for all conserved
