IMO it is not enough to say "obsolete documentation, someone should remove it". Some of us have been using *nix for years (or decades), and some of these facilities have been developed and stabilized years ago. We rely on things that used to work to keep working. At the very least, one should revise old documentation to clarify that some older method has been "deprecated" (as in java documentation), and the new method should be referenced, together with conversion methods and/or tools. We want to build on previous work. We don't want all of our sand castles to fall down.
In my case, I also find that _netdev does not work on a recent installation of Ubuntu 14.04.2 LTS (upgraded to .3) on Lenovo D20 (dual Xeon), but mysteriously it DOES work on a 1 y.o. installation (upgraded to 14.04.3 LTS) on HP 500-189 (AMD A10). That suggests to me that there must be some interaction(s) between packages? My old installation has everything (including the kitchen sink), but my new installation is rather spare (tho not exactly minimum). What is annoying is I want/need to NFS mount my /home directories on my new install as well. I will try autofs (waits longer, delaying during remainder of boot, until I try to login) instead of hard NFS mount during boot sequence. Still, it is annoying when things that used to work suddenly stop working.
