If you know which macs you will have, you can make an init script
which generate /etc/network/interface and /etc/hostname and /etc/hosts
the first boot and then remove itself.
Imagine:
$ cat /etc/machines
mac1 ip1 hostname1
....
macN ipN hostname N
$ cat /etc/init.d/10setnetworkonlyfirstboot
#!/bin/bash
mymac=$(ip add show dev eth0 | awk '/ether/ {print $2}')
myhost=$(awk "/$mymac/ {print \$3}")
myip=$(awk "/$mymac/ {print \$2}")
sed -i "s/IP/$myip" /etc/network/interfaces # and probably some
changes in /etc/hosts
sed -i "s/HOSTNAME/$myhost" /etc/hostname # and probably some changes
in /etc/hosts
rm -f /etc/init.d/10setnetworkonlyfirstboot
$ cat /etc/network/interfaces
auto eth0
iface eth0 inet static
address IP
network xxx
gateway yyy
$ cat /etc/hostname
HOSTNAME
Do you think this is a good approach ? It is not very elegant, but
maybe it works.
Regards,
