Yep, names like p4p1 are soooo much better than eth0 :-(

[Tom Horsley]

Especially when a new biosdevname package is installed and it
decides the name is no longer p4p1, but is now p6p1.

All the iptables rules that refer to the interface name
are broken.

The ifcfg-p4p1 file needs to be renamed and edited.

Wasn't the theory propounded that these new names
would cause less confusion?

(And why was having some disks named hda0 versus sda0
confusing, so we had to change all the names to sda0?
Can these two theories be made compatible? :-).
