Yeah, I'd like to know exactly how much of this can be expected to be in
other distros.  FWIW, I've been telling the LVM/device-mapper guys for a
long time to include udev rules etc. in the stock upstream release. I
know they are planning to do that but I'm not sure it's there yet. If
there is, please point me to it.

Anyway, that's the reason why I have my own prober, udev rules and
name-spaced properties. This will have to stay in the upstream
distribution of DKD until there's an upstream release of
LVM/device-mapper with what I need.

Thanks,
David
