Supports preconfigs which allow developers to store different system configurations (e.g. toolchain selection, kernel selection, package selection etc).
Supports profiles this allows just the userspace package set to be re-configured. This is excellent for autobuilding or exchanging the non platform specific configuration between targets.
All packages are built as rpms and managed using rpm
Target image files managed using a private rpm database per LTIB instance on the host
Supports single package developer mode using prep/scbuild/scdeploy analogs
Provides a means of source capture (patches) and auto update of spec files
Shell mode available to run all commands in ltib's spec environment
Incremental deployment (over NFS) supported
RAMDISK and JFFS2 Flash image creation supported
Read-only root filesystem supported.
LTIB is meta-data only, all sources are pulled using http and locally cached in a common area per-host.
Remote source pulls support proxys
Support for glibc and uclibc
All meta-data formats are open source (rpm, Linux Kernel Config)
Modular BSP architecture (easy to add new BSPs)
Support batch mode and --continue for auto-builders
Support --dry to preview ltib's actions
Provides --dltest to check for availability of sources/patches
Provides listpkgs mode to show all available packages, whether selected and their individual licenses.
Provides a release mode, this encapsulates an LTIB project into an iso images that will not require network access.

最近为了做mcf52277的板子，开始弄这个ltib，我觉得以后可以把所有的嵌入式linux开发都整合到ltib上来搞，以简化那些配置工作，应该能省很多精力。

我在fedora 7上安装m52277evb bsp，freescale的每个开发板都以ltib提供bsp包。下面记录下安装方法。

1. 把光盘或.iso文件（对于mcf52277evb来说就是M52277EVB_LTIB.ISO）mount到/mnt/cdrom:（注意用root身份）

mount /dev/cdrom /mnt/cdrom

2. 安装。先要切换到普通用户，因为ltib要求以普通用户安装，不要以root身份安装

su lzp

再安装：

cd /mnt/cdrom

./install

如果你顺利，这就完了，但我安装的时候出现了问题，报什么cp命令没有权限,但我检查了，确认所操作的目录我是有权限的rwx均有权限。实在奇怪，后来发现是fedora的那个selinux搞的鬼，在fedora的"系统”-》“管理”-》“SELinux Management”。把enforce mode从enforcing改成permissive。这样就ok了
