Thanks for the details.

Yeah, DFly only has vnconfig(8).  FreeBSD developed mdconfig that replaced
vnconfig (or updated vnconfig to be mdconfig).

But generally, you can just use vnconfig on DFly.

This is the normal state: vn, vn[0-4], md0 and md1.  I think you're using the
initrd(7) to mount encrypted root, so the initrd image uses the md0, then
the md1 is auto created.
