newsMount recognition problem, full hd install

I am testing 416, with a full hard drive install. It installed ok, runs ok, except that the partition that the pup is installed to displays as unmounted.
Earlier HD installation
Yeah, I do recall a problem here from before. Running an earlier installation, Upup 476, the desktop partition icon displays as mounted, which is correct. Running 'df' and 'mount' in Upup:
# busybox df

Notice that only the Busybox df gives the "right answer", and that is what my scripts use.
416 full hd installation
Now running all the same tests:

So, why does 'busybox df' now give the "wrong answer". I have upgraded Busybox, that's probably why!
The latest Busybox has become "more compatible", unfortunately. At least, that's my theory. So, to prove it, mounting the partition which has the older busybox, then try it:
# /mnt/sda3/bin/busybox df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sdb3 3850320 382132 3272600 10% /
shmfs 106844 0 106844 0% /dev/shm
/dev/sda3 9922400 5355756 4062608 57% /mnt/sda3
#
Yep, that's it. Now what?... I don't know how to fix it.
