[BusyBox] Endless corner cases...

[Rob Landley]

In _theory_, you could specify a _file_ in /etc/fstab with "loop" as one of 
the options and have it automatically loopback mount at a standard location 
for normal users, or via a mount -a.  Which means the fstab processing either 
has to go before the substitution of /dev/loop* for the blockDevice field, or 
the fstab code has to be aware of the difference between loopFile and 
blockDevice.

Don't mind me, just muttering to myself...
