Re: Does init start with any open files?

Well, that can't be right---I grepped the kernel source for "initctl"
and got no results. Besides, if you're running a shell, then init has
already had time to open and close whatever file descriptors it wants
to. What I want to know is whether init has any open file descriptors,
at, say, the moment its main() starts executing.
