Let me make sure.
- you add an rc script which executes ldconfig.
- init executes the rc script first of all.
- you didn't execute /filesystem/lib/ld-linux.so.2 in your linuxrc.
- and the result was unchanged.
Am I right?

Do you mean,
- /proc/mounts shows the bound mounts, which was bound AFTER chroot
- /proc/mounts never shows the bound mounts, which was bound BEFORE chroot
?

What I want to make sure is your first writable branch /etfw_changes is
NOT overlapped.

pivot_root and chroot? both?
How about stopping chroot? i.e.pivot_root and exit linuxrc.
