启动盘启动系统的时候报错，帮忙看一看吧？

antiblue

正常启动，内核和文件系统都正常解压缩，紧接着执行linuxrc的时候出错：
kmod: failed to exec /sbin/modprobe -s -k devfs.errno=2
mount:Mounting none on /nyroot/dev failed:no such device
n pivoting..
done,
mounting /proc
-install:applet bot found
ramdisk setup complete , stage separarion..
/linuxrc:55:cannot open dev/console:no such file
Kernel panic:attempted to kill init!


附linuxrc文件（行号是我加的）：
1   #!/bin/sh
2   # initrd Boot RC file

3   PATH="/bin:/sbin:/usr/bin:/usr/sbin"
4   TERM=linux
5   export PATH TERM
6   umask 022

7   /bin/busybox mkdir /nyroot
8   /bin/busybox mount -n -t tmpfs tmpfs /nyroot
9   cd nyroot

10  # copy over most of the filesystem
11  /bin/busybox echo "Copying to new filesystem."
12  for ii in /*
13  do
14        case $ii in
15        /lost+found|/nyroot|/proc|/dev)
16                ;;
17        *)
18                /bin/busybox cp -dpR $ii /nyroot/.
19                /bin/busybox echo -n $ii" "
20        esac
21  done

22  /bin/busybox echo "Done."
23  /bin/busybox mkdir initrd
24  /bin/busybox mkdir dev
25  /bin/busybox mount -t devfs none dev
26  /bin/busybox echo -n "ivoting.. "
27  /bin/busybox pivot_root . initrd
28  /bin/busybox echo "Done,"
29  cd /
30  /bin/busybox echo "Mounting: proc"
31  /bin/busybox mkdir proc

32  /bin/busybox mount -t proc /proc /proc
33  /bin/busybox --install -s
34  /bin/busybox echo "Ramdisk setup complete, stage separation.."
35  exec chroot . /bin/sh /scripts/stage2 <dev/console >dev/console 2>&1
36  echo "破破破, off bottom!??!"

另有/etc/mtab文件：
rootfs / rootfs rw 0 0
tmpfs / tmpfs rw 0 0
none /dev devfs rw 0 0
/proc /proc proc rw 0 0
