Mac OS X:跨网段Netboot

1最简单的命令：

/usr/sbin/bless --netboot --server bsdp://bootServerIP

2.复杂的

下面的可以定义更复杂的参数，适用于复杂的环境，把其中的前部参数都设置好。

#!/bin/sh    
## Set the following variables
server="server.school.edu"  # Enter IP or FQDN of netboot server   
sharepoint="NetBootSP0"    # Won't need to change in most cases 
setName="DeployStudioRuntime-intel.nbi"   # Enter netboot set name for Intel machines
ppcSetName="DeployStudioRuntime-ppc.nbi" # Enter PPC netboot set name - typically Tiger or Leopard
imageName="DeployStudioRuntime.sparseimage"      # Enter image name, if using DeployStudio, no need to change
protocol="nfs"  # Enter protocol, nfs or http
simple="false" -- If set to true, will boot from default netboot image
nextboot="--nextonly"
## You shouln't need to change anything below
if [ $simple == true ]; then
    if [ "`arch`" == "ppc" ]; then
        /usr/sbin/nvram boot-device="enet:${server}" boot-args="" boot-file=""
    else
        /usr/sbin/bless --netboot --server "bsdp://${server}" $nextboot
    fi
else
    if [ "`arch`" == "ppc" ]; then
        /usr/sbin/nvram boot-args="rp=${protocol}:${server}:/private/tftpboot/NetBoot/${sharepoint}:${ppcSetName}/${imageName}" boot-file="enet:${server},NetBoot//${sharepoint}//${ppcSetName}//ppc//mach.macosx" boot-device="enet:${server},NetBoot//${sharepoint}//${ppcSetName}//ppc//booter"
    else
        /usr/sbin/bless --netboot --booter "tftp://${server}/NetBoot/${sharepoint}/${setName}/i386/booter" --kernel "tftp://${server}/NetBoot/${sharepoint}/${setName}/i386/mach.macosx" --options "rp=${protocol}:${server}:/private/tftpboot/NetBoot/${sharepoint}:${setName}/${imageName}" $nextboot
    fi
fi
