Hi Jim!  ;-)
We're still a ways off.  We'll be sure to let you know.

It would be nice to get an idea of the lvm cmds you use and which
options.  Is it easy to grep through the code and find this or do you
have a list handy?

I know cluster info is here:
and upstream conga code is here correct?
cvs -d :pserver:cvs sources redhat com:/cvs/cluster checkout conga

I could not readily locate the upstream code for system-config-lvm.

We will do our best to maintain backward compatibility, especially in
areas we know people are already using.
