Imaging OS X
First of all which needs to be done is you need to get your image all ready. This can be by making sure the OS is upto date and clearing all rubbish and making sure all*relevant*software is installed.
Once this is done you need to take the image off. This can be done by doing many methods. The most easy way i find is *to use a Mac OS X DVD. You can use Disk utility from there. You can also you a USB/FIrewire bootable drive.
For this example I will be using the OS X DVD.
In case you do not know how to boot onto an OS X DVD you simply put the DVD in the drive. You then need to restart your Apple mac. Just before you hear the chime go hold down the C key on your keyboard.*I advice you hold it down until you see the wheel spinning around.*
Once you are into the OS X installation disk first press next on the first box that comes up. Then you need to go to the utility menu at the top and select Disk utility. Once in the disk utility you then need select the disk you wish to make a image of and select image at the top of Disk Utility. Once you done that you will then be asked where to store the image. I suggest you do this by putting the image on a external drive or another drive in the apple mac. I also suggest you use compression as images can get quite big.
Once the image has finished you then can go onto your admin computer or server.
In this example of using NetRestore I will be doing this from OS X 10.4 Server to make things easier.
Once you have plugged the firewire/USB drive into your OS X server you then will need to download the Netrestore utility. This can be found on http://www.howtomac.co.uk/index.php?...d=24&Itemid=38
Once downloaded you then need to run a program called NetRestore helper. In this application you can make the image file like we did with the OS X DVD but its complicated to use when you want to make a image of the drive you are using. When in NetRestore helper you need to click on the Create NetInstall Set tab at the top of NetRestore Helper.
In this part you need to name your image. For this example I will call my name "Macintosh OS_X_10_4_01022008" I always find it helps to date a image so i don't get confused. After that you then need to set the image ID this can be anything from 1 - 4095 i always go up in twos. For this example i will name this one "12". Also you can file a bit of a description in so for this example I will put in "OS X 10.4.11 with iLife"
Once you have filled in all these boxes you can add a few extra options by clicking the advance setting button. On this you can enable Remote Desktop so you can monitor how your image is going.
Once you have finished with all the settings you then need to click the pad lock and put in a Administrators password. When you have done that you can then click "Save NetInstall-Restore set" . You will then be asked where to save the net install. If you are using NetInstall of the Mac Server you will need to put it into /Macintosh HD/Libary/NetBoot/NetBootPS0/.
Near the end of the NetInstall set being made you will be asked if you wish to configure net restore say yes to this. You will then have the NetRestore tool open up. Within this you can set the options for the NetInstall for automated imaging. To do this you will need to go to Netrestore menu and then click preferences. If you wish to set a specificate image to install click under default configuration and select "Specify dynamic item.." Another box will appear and in this box you will need to name the image which you made. In this case I would put in "OS_X_10_4_01022008.dmg" Then click OK. If you wish to have full automation just click the Enable Full Automation Box. You also hav ea few other options to the right you can chose this if you like i tend to solect restart when finish and set target as boot disk.
When done just click save and you can then quite the NetRestore Utility. You will also need to unmount the NetRestore DMG image.
Now that the net install is done you then need to move the image file you made earlier to a folder in NetBootPS0 But first you need to copy some folders to the NetBootPS0 folder. If you go to the folder where you find Netrestore you will find several other folders within the netrestore folder. All you need to do is copy the "Resources" Folder to the NetBootPS0 folder located again in /Macintosh HD/Libary/NetBoot/NetBootPS0. Now you have the resource folder in plage you can now move the image you made ealier to the folder "/Resources/Disk Images/"
Now you have done all the above you now need to enable the image on server admin. To do this just go into the server admin software on the server and select the "NetBoot" service. You then need to go to the bottom tab and select settings and after that then select images. In this menu you will see the image which we named ealier. You will have the option to enable and make it default. if you make the image default any client machine which presses N on startup will start installing this image. If not selected within the Startup pane in System Preferences you can just select a image you want to install. When completed just click apply when your done.
Thats imaging with netrestore in a nut shell. Have fun
