[OpenAFS] How to uninstall AFS clearly

[wangkun@legend.com]

I am creating an AFS installation scripts.My environment is rather
simple,pc,Redhat7.0,and openafs-1.0.4. I uninstall AFS and install it again
for many times.But there are always some myterious problems which I can not
explain.I think my uninstallation script does not uninstall total materials
it should take away.The follow is the uninstallation scripts:

   rm -rf /etc/rc.d/init.d/afs
   rm -rf /etc/sysconfig/afs
   rm -rf /usr/afs
   rm -rf /usr/vice
   rm -rf /vicepa
   rmdir /afs
Did i omit something important?I need your advice.
