Are there any device nodes in the tar file? If this is the problem I
think it is, it's machine-independent and not new: vnodes created by
the bdevvp(9) routine -- e.g., the one from which the root filesystem
is initially mounted -- will be overwritten in place by the first
actual vnode with the same type and device number to be encountered.
Thus, an "ls -l /dev" before unrolling the tar file would likely
prevent the problem, by causing those device nodes to be run through
checkalias(9) first (I think; it's been a while since I last ran into
I am not at all clear on why *BSD behaves in this way.
(let ((C call-with-current-continuation)) (apply (lambda (x y) (x y)) (map
((lambda (r) ((C C) (lambda (s) (r (lambda l (apply (s s) l)))))) (lambda
(f) (lambda (l) (if (null? l) C (lambda (k) (display (car l)) ((f (cdr l))
(C k))))))) '((#\J #\d #\D #\v #\s) (#\e #\space #\a #\i #\newline)))))
