Labels are apparently not configured for the vn1 device.

It shouldn't have worked, because the vnconfig command doesn't enable
labels ("-s labels" option), and labels should be disabled by default.
The set/reset vnconfig options are sticky, so the above should work if
a previous vnconfig enabled labels; the only other thing it does wrong
is invoke vnconfig on the buffered device.
