I'm encountering a few problems while trying to come up with a 'cut down' Ubuntu install CD, and was wondering if anyone had any solutions/suggestions. The instructions found at <a href="https://wiki.ubuntu.com/InstallCDCustomizationHowTo">https://wiki.ubuntu.com/InstallCDCustomizationHowTo</a> don't seem to contain quite enough information to get everything working correctly, unfortunately. I manage to get through to the installation phase. At around 70% of the way through the installation process, 'installing intrd-tools' terminates with an error. Looking through /var/log/* indicates that an error occurred in the 'initramfs-tools' installation process. I suspect the apt-ftparchive step, in conjunction with the package signing process. The attached script demonstrates the problem.. Requirements: * A breezy install * A net connection, to grab the ubuntu-keyring source * breezy install ISO * gpg * qemu, to test the resulting install. * 6 gig of free space (in /tmp by default), for a temporary qemu install file, the destination CD iso image, and an extracted/modified copy of the CD * sudo password to mount the CD as a loopback device (and unmount). Modify the BASEDIR / CDIMAGE variables in the script, as appropriate. (NOTE: The signing passphrase is 'installtest') On install inside qemu, feel free to use a dummy IP address/config. The script will: * Generate a temporary gpg key for you * Grab the ubuntu-keyring source * Rebuild the package, signed with the temporary signing key. The error returned once ubuntu gets into the installation phase, will be: "Unable to install initrd-tools.. An error was returned while trying to install the initrd-tools package onto the target system." Any assistance would be appreciated. Once I get everything working, I'll modify the InstallCDCustomizationHowTo wiki page appropriately. Regards, Leigh.
