[overlayfs/bug] LXC ephemeral containers have "/rootfs" prefix in/proc/self/maps entries

[Bryan Wu]

Miklos,

We met a LXC issue [1] with overlayfs in Ubuntu, but with aufs it is gone.

I suspect it's related to the issue you mentioned in Documentation of overlayfs:
--
Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory
object in overlayfs will not contain vaid absolute paths, only
relative paths leading up to the filesystem's root.  This will be
fixed in the future.
--

Could you please help to take a look at this? or point me out some hints.
