[Linux-cluster] Minimum kernel version for cluster2.00

["David Shwatrz" <dshwatrz gmail com>]

Hello, 
 I saw somewhere (don't remember where - it could be on this list ) that cluster2.00  can be built with linux -2.6.20.
My question: is this kernel version, 2.6.20 , is a minimum version ? are there any chances that it will be built with kernel version 
lower thatn 2.6.20 ? couldn't find info about it in the source tarball of cluster2.00

Regaeds,
