That's because of my favourite change from the 2.4.3 patch:

-       strcpy(tsk->comm, "kupdate");
+       strcpy(tsk->comm, "kupdated");

noflushd 2.4 fixed this issue in the daemon itself, but I had forgotten about 
the generic startup skript. (Rpms and debs run their customized versions.)

Either the current version from CVS, or

ed /your/init.d/location/noflushd << EOF
%s/kupdate/kupdated/g
w
q
EOF

should get you going.

Regards,

Daniel.
