NetBoot Required Settings NetBoot Name:ĪutoImagrNBI will set this field to “ AutoImagrNBI,” this name is the name of the folder AutoImagrNBI will create for the NBI, as well as the name of the NBI that is shown to clients (except when running NetSUS as this shows as “Faux NetBoot”) NOTE: The Imagr URL is written to AutoImagrNBI’s plist for when you next run AutoImagrNBI. If you now click “Build”, & AutoImagrNBI will start the NBI creation process. The NetBoot Name field will now auto populate, in the format of “ AutoImagrNBI”, the “NetBoot Image Index” will be set to a random number & the “Serve Image over” options will be shown. Once the validation has run, AutoImagrNBI’s other options will become available. The output of which will show under the entered Imagr Configuration Plist URL. validateplistĪutoImagrNBI will now attempt to download the Imagr Configuration Plist & will check it via Imagr’s validateplist. Imagr gets its workflows from a plist that is accessible over HTTP, this URL needs to be set in Imagrs plist. Pressing “Yes” will download the latest release of Imagr from to a temp location & this version will be added to the NBI. Pressing “Release Info” will take you to the latest releases information on GitHub: If the app you upload is an older version than the latest release you’ll be asked if you wish to download the latest release. When pressing “Select” you are prompted to select an app to add to AutoImagrNBI, the version number of that is then reported back in AutoImagrNBI & if you have an internet connection that version will be checked against the latest release. You can either add a copy of the Imagr.app by pressing the “Select” button or you can download the latest release by pressing the “Download” button. If hdiutil can write to an image it has verified, attach will store an attribute with the image so that it will not be verified again unless its timestamp changes.” Imagr.app When selecting an OS.dmg for the 1st time, AutoImagrNBI may appear to “hang” This is as the OS.dmg is silently mounted using hdituil attach. The reason for this can be found in the hdiutil man page: “hdiutil attach attempts to intelligently verify images that contain checksums before attaching them. On selecting either, an OS.dmg AutoImagrNBI will attempt to get the OS.dmg OS X version & build number. To activate the other options, some items need to be added to AutoImagrNBI 1st. On Launch, AutoImagrNBI’s opens with some options are greyed out, this is by design. Imagr gets its workflows from a plist that is accessible over HTTP, therefore a web server is needed to host the Imagr Configuration Plist & associated PKG’s & DMG’s. Some NetBoot Servers do not support the NetBoot shadow files, & so a modified rc.netboot is needed.3rd Party Thunderbolt or USB adaptors might not always support NetBooting.If you have any issues in setting this far, the following (despite it’s age) is still the best resource to help you in “ Troubleshooting the NetBoot process.” Apple also has some documentation available.Įnabling verbose booting on a client can show where in the process things are failing. NOTE: 10.10 is the minimum OS Imagr will run on. 10.10+ NBI’s can be created on 10.9+ Macs running AutoImagrNBI. With AutoImagrNBI the OS versions do not have to match. NBI’s created with AutoImagrNBI really should be created from a clean never booted Operating System disk image (read: OS.dmg). This can be tested by creating a vanilla NetBoot Image via System Image Utility, once created upload it to your NetBoot server of choice. Or via Boot Picker which is accessed by holding the Option key on startup. Your mac clients need to be able to see you NetBoot server & any NBI’s hosted on it. These images can be seen via the Startup Disk pref pane: 8.19 Renames Sparseimage to DMG for hosting on NetSUS:ĪutoImagrNBI’s goal is to automate the NBI creation process, this will do you little good if you do not have the following things in place NetBoot Server Connectivity.8.15 Enables Disk Utilities Debug Menu:.8.7 Copies Imagr to the NBI’s Applications Folder:.8.6 Creates A Minimal Dock for Root Account:.8.4 Disable Screen Saver for Root account:.8.2 Suppresses Apple/iCloud & Diagnostics Setup Assistants:.1.3 Troubleshooting the NetBoot Process.
