Sure, and if you boot -s, that's where you end up.  Personally, I so
rarely shut *back* down to single user without rebooting that I tend
to even forget it can be done.

Clearly, though, winding somewhere else when you do migh be just as
confusing on the other side.

That example illustrates exactly where the chroot trick, nice though
it is, falls down: what happens when the flash widget is removed and
real-/ has to detach?  For that reason, you'd use the md.

Point taken, all the same.
