启动到这里会卡住，回车可以进入命令行

/mnt目录下有三个文件夹hd,nand1,nand2，其中nand1，nand2是我在编译之前手动添加进/rootfs/mnt目录的
我的fstab设置如下

proc  /proc      proc    defaults     0      0
none  /var/shm   shm     defaults     0      0
sysfs /sys       sysfs   defaults     0      0
none  /tmp   ramfs     defaults     0      0
none  /mnt   ramfs     defaults     0      0
none  /var   ramfs     defaults     0      0
##以下两行为编译前手动添加
/dev/sda1    /mnt/nand1 auto defaults  0      0
/dev/sda5    /mnt/nand2 auto defaults  0      0

执行mount -a后，提示
mount: mounting none on /var/shm failed: No such file or directory
mount: mounting /dev/sda1 on /mnt/nand1 failed: No such file or directory
mount: mounting /dev/sda5 on /mnt/nand2 failed: No such file or directory
/mnt目录下的文件夹全部消失
不执行mount -a，而使用mount /dev/sda1 /mnt/nand1命令可以成功挂载
请指点>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
