[yocto] Mounting USB drives on a "read-only-rootfs" based system

[Fred Ollinger]

There's also bind mounts as an option.


       The bind mounts.
              Since Linux 2.4.0 it is possible to remount part of the file hierarchy somewhere else.  The call is:

                     mount --bind olddir newdir

              or by using this fstab entry:

                     /olddir /newdir none bind

              After this call the same contents are accessible in two places.  One can also remount a single  file  (on  a
              single file).

FYI, I'm running 3.14 kernel.  Is this a job for aufs?  If so, how would I go about configuring it?

If you want to support arbitrary mounts then it's probably simplest to either change /media to be a symlink to /run/media, or put a tmpfs on /media.
