Ie, you can run ident on a FreeBSD 1.0 binary... I also believe it can be run on binaries from many other systems. So though we have lost the data in FreeBSD 14, the other data still exists, and though some might call this obscure, others of us find this data pricessless in figuring out from which a binary was made.
