I've included net.ifnames=0 on installer cmdline for every distro I've
installed for over a year. NAICT, Anaconda ignores it. I don't
remember exactly how on Fedora I get eth0, possibly as a result of
editing and renaming /etc/sysconfig/network-scripts/ifcfg-XXXX to
ifcfg-eth0, but from earlier installations carried forward into my
Rawhides I do have the following also:
-rw-rw-r-- 1 root root 0 Oct 4 2013
/etc/udev/rules.d/80-net-name-slot.rules
I see on
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterf...
that that name has inexplicably been replaced for systemd v209 & up by
80-net-setup-link.rules.
For the record, nmcli will do this without breaking a
sweat. For example:
[root@g55 ~]# nmcli con edit ed0fea4d-ed28-4fdb-9a8c-c131bd78d030
===| nmcli interactive connection editor |===
Editing existing '802-3-ethernet' connection:
'ed0fea4d-ed28-4fdb-9a8c-c131bd78d030'
Type 'help' or '?' for available commands.
Type 'describe [<setting>.<prop>]' for detailed property description.
You may edit the following settings: connection, 802-3-ethernet
(ethernet), 802-1x, ipv4, ipv6
nmcli> print connection
['connection' setting values]
connection.id: p3p1
connection.uuid: ed0fea4d-ed28-4fdb-9a8c-c131bd78d030

nmcli> set connection.id eth0

Connection 'eth0' (ed0fea4d-ed28-4fdb-9a8c-c131bd78d030) sucessfully saved.
nmcli> quit
[root@g55 ~]#
reboot when that is done, it will now be eth0 forever and ever, amen. A
word of caution, however - do not do this if you have already set up
other connections that depend on it, because they will still be looking
for the former devname - which brings up a feature request. Maybe
NetworkManager should have bridge, bond, and VPN connection masters
and/or slaves either use the UUID for the identifier, or update the link
in the underlying DB when IDs are changed.
