查看文件类型：

android/out/host/linux-x86/bin$ file ~/tmp/androidt/system.img 
/home/huaweishi/tmp/androidt/system.img: Linux rev 1.0 ext2 filesystem data, UUID=f2face5f-ed9a-59e5-b456-aa5e9dae14d0 (extents) (large files) (huge files)

挂载fail：

$ sudo mount system.img system
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

继续：

~/tmp/androidt$ sudo mount -o loop,ro system.img ./system
~/tmp/androidt$ cd system/
~/tmp/androidt/system$ ls
