Yes, but it's all died away after it was explained properly.

We can't do that, it'll break the "client-side". You can't do a client 
glusterfs mount without glusterfs at least.....

Okay, but the glusterfsd binary is only about 80k — that's tiny — and 
the symlink is only a few bytes.

And having the same bits in two RPMs could be a problem. I'll have to 
try it for myself and see, or perhaps Niels already knows, but I'd be 
worried that if I have both glusterfs-server and glusterfs-fuse 
installed and I uninstall -fuse it might remove them and break things. 
Not that anyone should uninstall -fuse without uninstalling -server.

That's already in process for Fedora, and will soon be proposed for the 
glusterfs.spec.in as well.

Good suggestion.
