android12L super.img 解压缩及其挂载到ubuntu18.04

本文介绍如何在Ubuntu18.04上解压缩高通平台Android12L的super.img，并将其挂载到系统中查看内容。

在源码的根目录下，执行如下命令：

out/host/linux-x86/bin/simg2img out/target/product/msmnile_gvmq/super.img super.img_rawmkdir superimgout/host/linux-x86/bin/lpunpack super.img_raw superimg/

查看superimg目录下的内容：

zjx@zjx:~/1T/release/superimg$ ls -al
total 4758796
drwxr-xr-x   5 root   root          4096 Dec  6 11:26 .
drwxr-xr-x   5 nobody nogroup       4096 Dec  6 11:22 ..
-rw-r--r--   1 root   root    1835712512 Dec  6 11:24 system_a.img
-rw-r--r--   1 root   root             0 Dec  6 11:24 system_b.img
-rw-r--r--   1 root   root     201793536 Dec  6 11:24 system_ext_a.img
-rw-r--r--   1 root   root             0 Dec  6 11:24 system_ext_b.img
-rw-r--r--   1 root   root    2851311616 Dec  6 11:24 vendor_a.img
-rw-r--r--   1 root   root             0 Dec  6 11:24 vendor_b.img

继续解压缩system/system_ext/vendor img文件：

sudo mkdir system
sudo mkdir system_ext
sudo mkdir vendorsudo mount -o ro system_a.img system
sudo mount -o ro system_ext_a.img system_ext
sudo mount -o ro vendor_a.img vendor

查看system system_ext vendor目录下的内容，即各img解压出来的内容：
