On my system, it's a 2TB disk.

Ummm, how could I post this output? In single user, read-only mode, I
don't think it got logged anywhere. I didn't take a picture. But I saw
lots of messages referring to "unexpected SU+J inconsistencies." I
remember the abbreviation sequence because I didn't know what it stood
for (and still don't understand 'soft updates').

Okay, this part I'm not remembering. It was FreeBSD 10/stable I was
installing (I made a disk with my notebook). I don't know if it was
sysinstall or bsdinstall.

Mine:

home# mount
/dev/ada0p3 on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
linprocfs on /usr/compat/linux/proc (linprocfs, local)

I had understood you to say that neither journaling nor soft-updates
were the default for the / partition. I'm not remembering if they were
presented as options in the install or if I selected those options.
(This isn't stuff I ordinarily think much about.)

If the the installation program presents the options, there's a
possibility I ticked the selection. I don't remember.

Ah. Okay. I was only looking at the gjournal man page.
