Hello Richard,
I had a similar issue. Typically, my notebook is connected to a dhcp network
and when I am travelling, like on the train or plane, I do not want to use
dhcp because it has to time out and the configuration will fail. When I am
travelling, I just set the network connection to a fixed ethernet address.
To solve the problem, I have written a startup script called netconfig, which
I put in /etc/init.d. The script uses an environment variable; NetConfig,
and files called, net-DEFAULT, and net-<config>, located in /etc/conf.d. The
files are copies of net modified for different configurations, i.e. a DHCP
configuration and a fixed IP configuration.
To get the script to work, I have installed it using "rc-update add netconfig
boot"...
The NetConfig environment variable is set via my grub.conf by adding something
like NetConfig=DHCP to the end of the kernel line. Now, my grub
configuration has multiple configurations...
I hope this makes sense. I have included several of my files as examples.
Let me know if you have any questions...
Sean
