Init.c, making it chroot

[M. Warner Losh]

this patch looks good, however, one nit:

is more succinctly expressed as:

+		if (stat("/dev", &stst) != 0)
+			warning("Can't stat /dev: %m");
+		else if (stst.st_dev == root_devno)
+				devfs++;

Also, kenv(KENV_GET, ... is used a lot.  Maybe it makes sense to have
a simple kenvget call.  Would make a few lines a little shorter if
nothing else.

Otherwise, I think this is a great patch.  I don't see other problems
with it.
