If you have very important file for security such like /etc/passwd, then the permission bits in the ro squashfs can be a problem. As you know, passwd file is world-readble but only an administrator can write. If you set it world writable in the lower ro branch and provide users aufs, then users can modify the file in aufs. Of course it is limited within the rw branch and aufs world, and highly depending upon the meaning of the file. And I just pointed out you may be able to -R for chmod. J. R.
