Yes, I did notice that inotify seemed to be working on an NFS share.

Ahh.  That would match the testing scenario I was working in.

So this is where fam is supposed to step in, right?  In particular
tracker should connect to a famd on a server that it is being asked to
index an NFS mount of?

If so, then that doesn't seem to be working here since I added an NFS
share and then checked the famd on the server the NFS share comes from
and it has no connections from my tracker machine:

# netstat -apn | grep 29707
tcp        0      0 0.0.0.0:627             0.0.0.0:*               LISTEN      
29707/famd      

Assuming I'm understanding all of this well enough.

Cheers,
b.
