Maybe this should be written as 'A info file that has the requested
network configuration' or something like that.

I think the intention here is to use the generated file as is. Depending
on the distro in the guest the file may need some processing. So I think
the actual interface name should also be part of the file.

While BOOTPROTO= is used in current network config files, its meaning
there is unrelated to what its meant here. Here it means DHCP=yes/no, so
I think the file should contain just that. And as the code is written
now BOOTPROTO= is optional, which is not mentioned in the comment.

I think this is not up to kvp_deamon to decide what controls the
interface. Maybe one day NM is sufficiently advanced technology that it
can cope with such requests?
The helper script should decide if the NM flag should be written to the
final config file.

This should mention that its either IPADDR=ipaddr1 or 'IPADDR=ipaddr1;
IPADDR_1=ipaddr2'

> +	 * DNSx=dns

This should mention that its either DNS=ipaddr1 or 'DNS=ipaddr1;
DNS1=ipaddr2'
