Let's say that I would like to get aligned to the new default, i.e. I
want to kill gridice on $SE_HOST.
I repeat my questions remained unanswered for now:
1) which RPMs have to be erased from the $SE_HOST, exclusively related
to this gridice service;
2) does YAIM remove RPMs no longer needed in the process of
configure/install of a node ? (and which might stay in the way of an
upgrade or a simple move of a service from one node to another -- like
this gridice)
3) does YAIM at least chkconfig --del <unwanted_services> ?
I would do such changes by hand, thank you very much, :-) , provided
that somebody answers (1)...
