RE: proposed changes to lvsd, nanny, pulse: seeking advice

It has been our experience, too, that community contributed patches don't seem to go anywhere.  And we would welcome them all.  Perhaps it can get a chance to penetrate via the Fedora channels?

Fred,

Submit bugs and patches using the Bugzilla interface:

  http://bugzilla.redhat.com.

I reported the issue about all nannies unexpectedly exiting if all Real Servers (for a particular service) are unavailable.  There's a patch in bugzilla, but to my knowledge it hasn't made it into TOT.  That was over
2 years ago.
