The Universities of Malaga and Seville use OpenGnsys to deploy macOS devices.
These devices do not allow booting via PXE, so they boot from the hard drive with a minilinux that requests the boot configuration via tftp. The server will send the PXE configuration for the OpenGnsys client to boot and display the home page.
To start a session from OpenGnsys, it will be necessary to restart the boot with grub, and it will go directly to the partition containing the operating system.
At the University of Barcelona, PAS equipment is managed centrally with OpenGnsys.
The boot is usually done from the hard drive; when maintenance is to be performed, it switches to network boot to display the OpenGnsys start menu.
Upon booting the equipment, just as the hard drive configuration is obtained, a shell script is executed that leaves data about the hardware model accessible by the server.
The start menu takes this data and displays the images available for that hardware and a form with the post-configuration data
The version of OpenGnsys 1.1.1 Espeto allows managing UEFI devices with Secure Boot enabled.
Efforts have been made to ensure that the management of UEFI devices affects the use of OpenGnsys as little as possible, so that the user does not have to modify their way of working.
Features and limitations of version 1.1.1:
OpenGnsys is currently being used to manage over 44,000 devices. The data speaks for itself.
