This is Linux, not BSD.

Of course, I've never heard of Linux being able to do crash dumps.

Since I don't have a laptop running Linux, I've never had reason to
examine this.

Can the STD partition be the same as the swap partition?

That's weak.  OpenVMS is able to send crash dumps to pre-created
special files.

Of course, Linux not being able to do crash dumps at all is even weaker.
