Customizing Ubuntu Image with UCK

UCK stands for Ubuntu Customization Kit: https://launchpad.net/uck

We can use PPA to install it:

And you’ll find it in under “System Tools” section of your menu. Follow the wizard to create your own Ubuntu image. It will extract your Ubuntu image, and also the squashfs on it. 5G free disk space is required under ~/tmp. The final customized image locates as ~/tmp/remaster-new-files/livecd.iso.

I tried to use a 10.04.4 image as base image. It ends with message:

Don’t worry. The final image is already created. isohybrid is in syslinux package 3.72 and later. But Ubuntu 10.04 has only 3.63.

Now you can use the image like the source image. Either burn it or use it to install from harddisk. I integrated all Chinese supports, codecs and some development tools. See screenshot of my livecd:

I used to have lrcshow-x, but it seems to be hard to install and do not cache lyrics locally. From the osdlyrics download file list, use the 0.4.0 version for Ubuntu 10.04 (Lucid). Newer versions are broken in MPRIS2 protocol handling, see here.
