I installed the debian/etch packages from Oct 06 and no longer see "bad

But I can't detect in the cibadmin -Q output any trace of the set
attributes!
Where should they be located ?
Do I have to initialize them manually so that pingd can update them? How?
BTW: the output of the SysInfo clone-resource is there:

/usr/lib/heartbeat/pingd -U -a pingd-internal -d 5s -m 1000 -h 172.17.32.23
does not generate any output  on the console.
The -U switch does not appear in pingd --help.
