networking config being overwritten at startup

[phil at pjd.me.uk (Philip Downer)]

Hi,

I'm trying to build a live cd for a system with several interfaces and 
with other custom settings in it's /etc/network/interfaces file, I'm 
using live-helper built from git and building a system based on etch. 
The problem is that when I boot the cd the /etc/network/interfaces file 
is not my custom one, it only lists lo, eth0 and the system has only 
brought those interfaces up.

I have added the custom /etc/network/interfaces file into 
config/chroot_local-includes and when I build the system I've enabled 
verbose output, debugging and interactivity. When I get the interactive 
prompt during the build of the system I can see that my 
/etc/network/interfaces file is the one which I have added and has not 
been altered, I did for a while think that this may have been the cause 
of my problem:

mksquashfs: file chroot/etc/network/interfaces, uncompressed size 367 
bytes DUPLICATE

i.e. the duplicate file might have overwritten my one (assuming the 
duplicate status is just going by filename).

However after uncompressing and inspecting the squashfs file system in 
binary/casper (and just to make sure I also checked the 
filesystem.squashfs that is in the fully generated iso) I have found 
that the etc/network/interfaces file is my custom one.

Can anyone point me in the right direction as to what might be 
overwriting the /etc/network/interfaces file from squashfs or offer any 
other solution to enable a custom network setup.


Regards,

Phil
