I'm trying to get the interface on a multi-homed machine named

Is that the full ifconfig output for that interface or does it have
the right IP address as well?
I haven't connected the port yet. Before I do I need to make sure I've
got the correct internet name.
That's the device (ethernet port) name, NOT the host name. The host name
is controlled by the contents of the /etc/hostname file, which is read
at boot time and sets the FQDN (fully qualified domain name) of the
machine.
That was fat finger syndrome. I meant interface name !
The stuff in the /etc/sysconfig/network-scripts/ifcfg-* files (and NM's
configurations) control how the interfaces themselves are configured
and do not affect the hostname of the machine.
As I understand, NM scans the ifcfg files for HWADDR's. If there's a
match, it names the interface the DEVICE name.
I believe NM uses the DEVICE _or_ the HWADDR to set up the interface.
Whichever one matches the hardware config first is what gets used (I'm
not sure which has precedence). And don't be confused...the values in
the NM config are only used to match the hardware.
And in answer to your second message, NM doesn't do any renaming of
devices. That's still done by the udev rules.
If so, why doesn't the udev rule work ? But I think nm now does device
renaming:
