Trouble mounting NFS shares in %post script of a kickstart FC6 install

Just in case anyone is wondering...

It turns out that somewhere along the way during a kickstart install  
for FC6, the portmap program is killed, so by the time the install  
gets to the %post script, NFS mounts can't happen.  I found this out  
by looking at the F4 terminal messages that indicated that the mount  
operation was trying to contact the portmapper on localhost.
