http://fedoraproject.org/wiki/QA:Testcase_NetworkManager_assume Booted off the 2009-08-13 test day live CD, there obviously was no ifcfg-eth0. There was no system-config-network that could be used to configure eth0 either (just the console mode app and I couldn't figure out how to do this with it), installed system-config-network (the GUI one) and managed to create the connection. No matter what I tried (plain NM restart, NM stop - /etc/init.d/network start - NM start - NM stop), stopping NM brought down my eth0.

Niels, yes I noticed bug 517229 before submitting this one. Why I reported another one is that 517229 contains so little information (whether /etc/init.d/network was run for instance, and whether the connection was configured via system-config-network and had a ifcfg-eth0 file) that it's not possible to say whether it's the same issue. I *guess* the NM developers need that info.
