Setting tag NodeManager-2.0-10

Setting tag NodeManager-2.0-10
(1) unconditionnally install and chkconfig-like a generic 'vinit' service
that triggers /etc/init.d/vinit.slice if present and executable
(2) install the slice-provided initscript (as per the initscript tag) as
/etc/init.d/vinit.slice
(3) as a result the initscript are now triggered by rc as part of the
standard vserver .. start, properly attached to the vserver,
and properly killed upon vserver .. stop
(4) this works best with util-vserver-pl 0.3-31 or 0.4-12
