[Linux-cluster] GFS can be used as root filesystem?

As anyone attempted to use GFS client on diskless Linux node to act as
its root file system?
 
Thinking about the dependencies of GFS, the likes of CMAN, clvmd, gnbd
(if needed) should start before GFS during the boot up process. But the
concern is CMAN would need to read /etc/cluster/cluster.conf file which
won't be available. Other components might need something from
filesystem too, like CLVM might look for lvm.conf. Sounds like a chicken
& egg problem. 
 
As anyone got around these aspects and able to use GFS mount as a root
filesystem?
 
Appreciate any ideas on this.
 
thanks,
Sridhar
