Whether NFS is running or not, nfs-utils tries to stop the service when removing
the package. Because output is not redirected this causes ugly stuff to show up
on the screen. It should
A) contitionally stop (if possible)
B) redirect output
See http://fedoraproject.org/wiki/ScriptletSnippets section Services.
Fixed in nfs-utils-1.0.12-2.fc7
