How did the systemd cabal manage to mess that up? I ditched that thing a while ago for good reasons, so I don't keep track anymore.

I'm not entirely sure of everything, but problems with UUIDs (which we expected), and some dbus signals not being generated when run over a NFS mounted root causing the boot to hang. We hacked some timeouts to get around the problem but never figured out exactly where the signals were supposed to be generated from. A hint if you're doing this on Linux. We PXEBoot an iPXE loader to boot the machines. Doesn't work properly on UEFI unfortunately, gotta use BIOS boot. If it helps, I have notes on how to set that up: Go to http://rom-o-matic.net http://rom-o-matic.net and choose gPXE git. Click on the "Customize" button to expand all of the options. Choose: 1.
