biosdevname strikes again :-).

[Tom Horsley]

Aside from the 3 or 4 updates to biosdevname that changed
the "immutable" names, I've just found another fail:
I replaced my motherboard and since this one has native
gigabit, I didn't re-install the separate NIC.

Naturally, my one and only ethernet interface
is now called em1 instead of p6p1.

This really worked infinitely better before they
solved this problem. All I had to do was remove
the 70-persistent-net udev file and let it get
automatically regenerated from scratch.

Also "yum erase biosdevname" does not work with live-cd/install-cd/etc.

F18 still stands!

Yea, that works for f18, but in f19, they have yet another
immutable name generator so that if you merely erase biosdevname
you wind up getting this new thing which generates even more
descriptive names, something like "erdxq27p" (OK, I made
that up :-).

And as near as I can tell the udev rule that would generate
the 70-persistent-net file for me is utterly gone, so
I have to dig up cryptic syntax to make my own persistent
name file.

All-in-all, it is easier to just rename things when
biosdevname changes them (though it would have been
even easier if know one had ever thought of this nonsense
in the first place).

yum erase biosdevname ;)

Boot with "biosdevname=0" or "biosdevname=0 net.ifnames=0" and use 
eth[0,1..] as before.
