hmm, i've now created a /initrd directory to let the the change_root of
the
initrd work correctly.

and then i looked with fuser, what processes reference the initrd:

---
root@ws4:~ $ fuser -mv /initrd/
 
                     USER        PID ACCESS COMMAND
/initrd/             root         67 .rc.. 
rpciod                                                                                         
---

only the rpciod references the initrd, none of the other
kernel-threads.

Regards,
  Daniel
