Hi,

Your use case is for when ~/.local (for instance) is a separate mount
point (an uncommon use case because mounting file systems on Linux
usually requires root privileges).

I’d suggested “dedicated device” → “underlying device is busy”, and a
short comment above explaining the kind of situation where this can
occur.

Thanks,
Ludo’.
