Of course, these locations need to move around every few years, otherwise 
people would be expecting things to remain in place...

I'd rather keep using the /media symlink, as it gives distributions a chance 
to move things around.

On the satellite settop boxes, /media is a 64k tmpfs mount. This is because 
when a mount fails, the box may end up writing a TV recording to wherever 
/media happens to be. It that's flash or a big tmpfs, the box will commit 
suicide in mere seconds by either filling the flash or eating up the precious 
RAM. And for some things, the box really needs a big tmpfs, so just reducing 
the volatiles' sizes wasn't an option.

Having said that, if this is blocking, I'll do a s./media./run/media.g on the 
file, getting this mainlined has higher priority.
