Here is the list of services I've shut off:
setroubleshoot sendmail rsyslog rpcidmapd rpcgssd rpcbind portreserve
nfslock netfs mdmonitor kerneloops irqbalance cups bluetooth avahi-daemon
auditd
I admit, I'm not completely sure about all the rpc stuff I'm shutting off,
but it doesn't seem to have an adverse affect.
