Thanks J R Okajima, Excuse me for my inadequate explanation of the problem. I am following the below link for the Read only implementation. [1]https://matt.bionicmessage.net/blog/2013/03/26/HOWTO%3A%20Read%20only%20r ootfs,%20writes%20to%20USB%20on%20Linux  Now after the switch_root call from init of initramfs the mount /rw /ro and /aufs are cleaned. exec switch_root /aufs /sbin/init
The mount point is not accessible ,Please correct me if my understanding is wrong.

I don't understand what you want to ask. You can mount aufs with three branches before and after switch_root. Both ways are possible. What does it mean "hence I miss the /aufs in initramfs"? J. R.
