@lattera@bsd.network There are only two hard problems in computing: Caching, Naming and Overflows :-) I did waffle on that for some time, but I decided I wanted to name the facility and the kernel implementation differently, so people would not think about them as a single unitary thing, but as a facility and one (of possibly more) implementations of that facility. As in: Other implementations could jail processes in a gaol, an arrest, a stockade &c. &c. It came about because I always felt that both UNIX and MINIX implictly discouraged filesystem research, by always talking about "the filesystem" - as if there could only be one.
