Re: available resource declaration language(s)

[carlos manzanedo <cvsrep@wanadoo.es>]

As you say in the kernel list ,I also think that it should be discussed
about how about to standarize the way that clusters affect the kernel
and how they find each others.But i don't see any discussion in the
cluster list that Rick create.
May be people of mosix team could contribute the discussion and start to
explain what they think about the way to standarize different clusters
in the kernel.
