Well, not having a self-booting device other than DF0:, I just believed the
docs that said that's what it was.

AmigaDOS technical reference manual, page whatever. Under "CurrentDir":

"A value of zero is a valid result here and indicates that the current
directory is the root of the initial startup disk."

It's a pity that the REST of the system isn't set up to reflect this and
treat 0 as df0: or a no-op. It's a bit of a shocker to guru because you've
Unlock()ed CurrentDir().
