Apologies for the ambiguity!

/dev/da0s1 on /boot/msdos (msdosfs, local, noatime)
is the normal dos filesystem on the root USB device.
Normally it is mounted, IME.

/dev/mmcsd0s1 on /mnt (msdosfs, local)
was where I mounted the microSD DOS partition
so the contents could be listed. This is a Pi2 
so a DOS microSD card is required to boot from USB.
Normally /dev/mmcsd0s1 is not mounted when root
is booted from USB.

Mostly I wondered if files placed in an "unused" DOS
subdirectory could be hidden from the boot software.
It was a poor way to pose the question.

At the moment the armv7 PATA disk is updating. If it boots
the Pi2 successfully I'll try it on Pi3 and Pi4. If
that works I'll set up a SATA armv7 disk and test the
troublesome disk enclosures. 

Thank you!
