Hello List, hello Alain,
I am playing around with the "udpcast image generator" and I need to store the next-server address in the filesystem for later processing. I am using kernel-udpcast_2.6.30-rc5_all.deb and udpcast-mkimage_20081213_all.deb.
This is what my dhcp.script looks like: === snip === #!/bin/sh
[ -n "$broadcast" ] && BROADCAST="broadcast $broadcast" [ -n "$subnet" ] && NETMASK="netmask $subnet" case "$1" in deconfig) /sbin/ifconfig $interface 0.0.0.0 ;; renew|bound) /sbin/ifconfig $interface $ip $BROADCAST $NETMASK /sbin/echo $siaddr > /etc/server.ip ;; esac === snap ===
This works as expected when generating cd-images. If I generate a initrd and boot via PXE, the file /etc/server.ip never gets created. I tried to create the file in many places (/tmp, /sbin, etc.) but it doesn't work.
Is there something important that I am missing? I thought that there is no difference between a cd-image and a plain initrd (besides syslinux/pxelinux and the kernel being separate).
Additionally FYI, when using the latest kernel and mkimage I get some weird behaviour. I use VirtualBox 2.2 for testing purposes and both cd-image and initrd crash the VM when trying to write to the filesystem from within dhcp.script.
Any help/suggestion is much appreciated.
Thanks in advance.
