My old package added/removed "-cf /etc/ltsp-dhcpd.conf" in /etc/sysconfig/dhcpd
in %post/%postun. It worked, but strikes me as horribly wrong - how many would
think of looking in /etc/sysconfig/dhcpd to figure which conf file dhcpd is
using? Breaking it out as a separate init script at least makes it a bit more
obvious what is going on...

%post

CF_OPTION="-cf /etc/dhcpd-k12ltsp.conf"
CONF_FILE="/etc/sysconfig/dhcpd"

if [ -f $CONF_FILE -a -f /etc/dhcpd-k12ltsp.conf ]
then
   # change dhcpd.conf.k12ltsp to dhcpd-k12ltsp.conf
   perl -i -p -e "s,dhcpd.conf.k12ltsp,dhcpd-k12ltsp.conf," $CONF_FILE

   if [ "x`grep -- -cf $CONF_FILE`" = "x" ]
   then
      . $CONF_FILE
      NEWARGS="$DHCPDARGS $CF_OPTION"
      perl -i.ltsp -p -e "s,DHCPDARGS=.*,DHCPDARGS=\"$NEWARGS\"," $CONF_FILE
   fi
fi

%postun

CF_OPTION="-cf /etc/dhcpd-k12ltsp.conf"
CONF_FILE="/etc/sysconfig/dhcpd"

if [ -f $CONF_FILE ]
then
   if [ "`grep -- -cf $CONF_FILE`" ]
   then
      . $CONF_FILE
      NEWARGS="`echo $DHCPDARGS | sed -e \"s,$CF_OPTION,,g\"`"
      perl -i.ltsp -p -e "s,DHCPDARGS=.*,DHCPDARGS=\"$NEWARGS\"," $CONF_FILE
   fi
fi
