I'm confused: how on your system does a given executable know when to
use /export/fs/lib and when to use /lib? (What do you mean by "lib is under
the /export/fs"? Presumably there's a lib directory in there, one that's

Do you mean init continues to run after the mount, but it was execed before

You just said that when you built busybox with shared libraries, you can
always run /sbin/init. You you're giving circumstances under which you
can't? I'm guessing that by "restart the target" you mean reexec init after
the mount? (Or else the version on the target is now statically linked, and
that's what's different?)

I'm still trying to understand how your system is set up and what you're doing
