OK, good. I guess that means that the lvmutils (even the
patched version in the RPM) are heavily broken ...

Andrea, could you send me the patches you use to make your
LVM utilities work? Then we'll be able to put together at
least one working LVM utilities version ;)

Heinz, how about releasing a 0.8.1 version of the utilities
so that there is something WORKING out there? Not having
working LVM utilities available is an utter disgrace when
all the code to make it work is just available...

regards,

Rik
