git

Enhanced shell prompt
One specificity of git over something lke subversion is that all your branch stay in the same directory.
Thanks to the git completion extensions available in git-core, you can enhance your shell prompt to display the name of the branch you are working on. For example, if you set:

PS1='\u@\h:\w$(__git_ps1 " (%s)") \$ '

uck-remaster是UCK的流程文件，我們可以在」customizing」段加入自定義腳本。

UCK腳本調用流程(參見: uck-remaster文件)：
1. 解壓鏡像文件:uck-remaster-unpack-iso
2. 解壓初始化鏡像: uck-remaster-unpack-initrd
3. 解壓根文件系統: uck-remaster-unpack-rootfs
4. 調用自定義腳本。
5. 壓縮初始化包: uck-remaster-pack-initrd
6. 壓縮根文件系統包: uck-remaster-pack-rootfs
7. 製作鏡像文件: uck-remaster-pack-iso
8. 清理: uck-remaster-clean
