Maybe something is wrong with opkg, it only happens when files are in 
/var/lib/foo, here is a *workaround*:

diff --git a/meta/lib/oe/rootfs.py b/meta/lib/oe/rootfs.py
index a348b97..ba072c0 100644
--- a/meta/lib/oe/rootfs.py
+++ b/meta/lib/oe/rootfs.py
@@ -951,7 +951,7 @@ class OpkgRootfs(DpkgOpkgRootfs):
          if self.progress_reporter:
              self.progress_reporter.next_stage()

-        self._setup_dbg_rootfs(['/etc', '/var/lib/opkg', '/usr/lib/ssl'])
+        self._setup_dbg_rootfs(['/etc', '/var/lib/opkg', '/usr/lib/ssl', 
'/var/lib/nfs'])

          execute_pre_post_process(self.d, opkg_post_process_cmds)


This is not a regular fix, you can file a bug here:
https://bugzilla.yoctoproject.org/

We may fix it later.
