We have Gateway Manager for GSX installed on a Mac Pro. Also, we have macOS Server setup on it as well. Everything used to work just fine for net booting. Suddenly, it stopped allowing Netbooting. I'm thinking it had to do with the Server App update or when upgrading to High Sierra. I can see all the NetBoot NBI's in the boot manager on the Mac I want to NetBoot from. When I select the correct NBI I wan't to boot to, it just boots straight into it's internal HD. I can get NetBoot to work fine on a Linux box but for whatever reason, something with Apple has changed something.
Anyone experiencing similar issues?
Yeah, I have seen that. However, Gateway Manager will only run on macOS which requires NetBoot in order to use it. If I could run it on Linux too, I'd be more than happy to move away from macOS "Server" all together. So, it's still technically there in the server app, just hidden. I can't imagine Apple would deprecate something that would cause one of their other products to stop working without an alternative.
if it ain't broke.....
I have no plans to update my apple server app as I still require the need to netboot. The other "solutions" don't appeal to me, but I imagine that I will have to make a decision before too long. My system is working fine, I don't want to have to re-invent the wheel around here damn it
