[Linux-cluster] CLVMD without GFS

This is mainly due to clvmd init script that activates all the VG's it
I kind off have a problem with all those init scripts (including rc.sysinit)
that want to automatically do things
that an admin (well myself ;-) ) wouldn't like them to be active.
Ideally, there should be a file (/etc/sysconfig/clvm.conf) that contains
only what we want to automatically activate at startup. If empty everythings
I have the same problem with automatic cluster startup, it is something
that, IMHO, could lead to undesirable situations (imagine the node that
keeps on rebooting after automatic join the cluster).
