使Squashfs可写的办法

yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ pwd
/home/yiyi/Applications/Office2016
yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ ls
lower  Office2016  Office2016.squashfs  upper  work
yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ 

该目录下是几个子目录和一个叫Office2016的Squashfs镜像文件

我们mount这个squashfs文件：

yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ sudo mount Office2016.squashfs lower
yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ ls lower
dosdevices  drive_c  system.reg  userdef.reg  user.reg

然后可以看到我制作的Office2016的Wineprefix。

然后我们

sudo mount -t overlay Office2016 Office2016   -o lowerdir=lower,upperdir=upper,workdir=work 

检测一下～

yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ mkdir Office2016/1
yiyi@yiyi-HP-Pavilion-Notebook:~/Applications/Office2016$ ls Office2016
1  dosdevices  drive_c  system.reg  userdef.reg  user.reg

可以看到我的Squashfs已经可写
