The beauty of using the InstaDMG process is that I can then use the base image on PPC and Intel hardware without having to utilize two different images. And, the beauty is that I can use that same exact image to be my NetBoot image.<div><br></div><div>For those that don't know about InstaDMG, head on over to AFP548.com and start with Josh's discussion on imaging:</div><div><br></div><div><a href="http://www.afp548.com/article.php?story=ImageCreationRevolution&query=revolution">http://www.afp548.com/article.php?story=ImageCreationRevolution&query=revolution</a></div><div><br></div><div>Then move on to the the webcast held on MacEnterprise.org for InstaDMG:</div><div><br></div><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><a href="http://www.afp548.com/article.php?story=20080414170557450&query=revolution">http://www.afp548.com/article.php?story=20080414170557450&query=revolution</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">Or the MacWorld show presentation by Joel Rennich and Josh Wisenbaker:</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><a href="https://www.macworldencore.com/online/presentation.asp?sessionTypeId=1&trackId=4">https://www.macworldencore.com/online/presentation.asp?sessionTypeId=1&trackId=4</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">If you've already been thru this, I'm sorry for re-posting these links.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">I took an InstaDMG created image, mounted it on the desktop of my Leopard server, added the Casper suite to the Applications folder (and took out apps I didn't need), re-saved the image, then re-mounted it and ran it thru the System Image utility in Leopard. I can now NetBoot any machine I want, PPC and Intel, with the one image and use it to re-image using Casper. Now, of course, this is not an automated NetInstall, so it does require the "right size bolts", as Siddhartha mentioned, but it will work. And the image has worked flawlessly on each computer I've installed it on.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">A word of advice when it comes to the InstaDMG build train: make sure you utilize the clearReg.pkg script to clear the intro video:</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><a href="http://www.afp548.com/forum/viewtopic.php?showtopic=20312">http://www.afp548.com/forum/viewtopic.php?showtopic=20312</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">I would agree, however, that multi-cast is the preferred method when dealing with that large a number of machines. I would also suggest, as Siddhartha mentioned, if possible get them all on a segmented network. If you can setup a "build room" with a machine running 10.5 Server, a Gigabit switch, and all of your machines, that's the way to go. I have found in the past that doing it this way, even setting up a MacPro or G5 with Leopard Server running on it, I could image 20 machines in about an hour or so.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">I'd be interested to see how everyone manages this, and how it goes. I know for me the issue is preserving user content on the machines. The person that was in here before me did not move users to network home folders, so I have to do upgrades one at a time so that I can preserve the user data. That is, until I write the scripts necessary to move the data before using Casper to doing auto-magically. Anyone have any scripts they want to share? :-)</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; "><br></div></div></div><div><div apple-content-edited="true"><div><div id="sig"><div class="row"><strong>Steve Wood</strong> <br> Director, Information Technology <br> <a href="mailto:swood@integerdallas.com">swood@integerdallas.com</a> <br><br> The Integer Group | 1999 Bryan St. | Ste. 1700 | Dallas, TX 75201 <br> T 214.758.6813 | F 214.758.6907 | C 940.312.2475 <br> <br> <img src="http://extranet.integerdallas.com/Integer/signature/green.jpg"> <br><br> </div> </div></div> </div><br><div><div>On May 13, 2008, at 1:13 AM, Siddhartha Chadda wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><br><font size="2" face="sans-serif">use the right size bolts to press the n key.</font> <br><font size="2" face="sans-serif">start netrestore, netinstall whatever at the exact same time on 50 machines at a time.</font> <br><font size="2" face="sans-serif">no problem.</font> <br><font size="2" face="sans-serif">also do it on a seperate segmented network.</font> <br><font size="2" face="sans-serif">if all machines are making the exact same request to afp and all afp reads are from memory not disk things go faster.</font> <br><font size="2" face="sans-serif">did this at hopkins many moons ago.</font> <br><font size="2" face="sans-serif">i wonder if they still do that? respond. you know who you are.</font> <br> <br><font size="2" face="sans-serif">see these photos.</font> <br><font size="2" face="sans-serif">look closely for the bolts!</font> <br><a href="http://weblogs.hopkins.k12.mn.us/onetoone/wp-content/uploads/laptopimaging.jpg"><font size="2" face="sans-serif">http://weblogs.hopkins.k12.mn.us/onetoone/wp-content/uploads/laptopimaging.jpg</font></a> <br> <br> <br> <br><font size="2" face="sans-serif">Siddhartha Chadda<br> Chief Technology Officer<br> OLSON<br> T:612.215.3533<br> C:612.986.9310<br> E:<a href="mailto:schadda@oco.com">schadda@oco.com</a></font> <br> ______________________________________________________________________<br> This email has been scanned by the MessageLabs Email Security System on behalf of OLSON.
