At last week's MUUG meeting, during the round-table discussion, I mentioned some of the feature and problems I had encountered with Fedora 16. A couple people mentioned the fact that network device naming had changed.

Here's more about that in the Fedora 15 release notes, including suggested workarounds and a way to disable the feature entirely:
