The issue is that e2fsprogs gets compiled for systems other than just
Linux.  I don't want to be like the assholes who work on systemd and
GNOME that simply screw over *BSD systems.  This is why I keep our
internal version of blkid in e2fsprogs, even if I do plan to use the
system blkid by default for 1.43.

If I had infinite amounts of free time, I'd backport the the new
blkid_probe interfaces to our internal version of blkid, but since I
don't, I prefer use the old interfaces for blkid as much as possible,
since that's the path of least resistance in terms of continuing to
support non-Linux users of e2fsprogs.

How do you disable probing for superblocks with the new blkid interface?
