How do I get the filesystem which is shadowed by another file system ?? For
instance , ext3 is mounted on /root mount point. But this is alo a mount
point for rootfs (which is not unmounted ,AFAIK) .
AFAIK, you can't, unless you already open the file(s) and save the
file descriptor(s) which is shadowed.

As a userspace kludge, you might be able to remount the root node of
the shadowed branch to another leaf node and then follow dirents
recursively, saving inodes of shadowed directories as you go. It's
VERY ugly, and I'm positive that there's a kernel side way to do it
elegantly, but I don't know how. I figured I throw the idea out there
and see if you can derive a better method... I'm just shooting from the
hip, as I don't know anything about file system level stuff.
