Problems with System Image Utility in El Capiton
Since upgrading to El Capitan, I haven't been able to create a NetInstall Boot Image. I am trying to create the .nbi on a standalone computer with El Capitan installed on it and also Server.app version 5.0.4. I have the same version of Server.app on the computer setup as our Server, but still running Yosemite 10.10.5 on it. I can create the .nbi from the standalone computer with the El Capitan installer on it, but then I try to copy it to the NetBootSP0 folder on the Server and receive the message "The Finder can't complete the operation because some data in "booted" can't be read or written. (Error code -36)". I have completed this process in prior OS X versions and System Image Utility without issues. I know the El Capitan version of System Image Utility has more options available, I have not changed any from the default. I also tried saving the .nbi folder directly to the Server NetBootSP0 folder to see if that would work, but I was unable to boot to it from a standalone computer after it was created. Is there one of the settings that I need to change in creating the .nbi or something else I should try to get the NetInstall image to work correctly. Thank you.
Mac mini, OS X Yosemite (10.10.5)
