master - branch intended for the RTEMS master which tracks the FreeBSD master branch. This branch must be used for libbsd development. Back ports to the 6-freebsd-12 are allowed.

6-freebsd-12 - branch intended for RTEMS 6 which tracks the FreeBSD stable/12 branch. This branch is maintained and regular updates from FreeBSD are planned. It is recommended for production systems.

5-freebsd-12 - branch belongs to the RTEMS 5 release. It is based on FreeBSD stable/12 branch. It is recommended for production systems that use RTEMS 5.

5 - branch belongs to the RTEMS 5 release. It is based on a FreeBSD development version.

freebsd-9.3 - branch for some RTEMS version with a FreeBSD 9.3 baseline. This branch is unmaintained. It is recommended to update to RTEMS 5 or 6.

4.11 - branch for the RTEMS 4.11 release series. This branch is unmaintained. It is recommended to update to RTEMS 5 or 6.

 SYSINIT

SYSINIT是一个通用的调用排序与分别执行机制的框架。FreeBSD目前使用它来进行内核的动态初始化。SYSINIT使得FreeBSD的内核各子系统可以在内核或模块动态加载链接时被重整、添加、删除、替换，这样，内核和模块加载时就不必去修改一个静态的有序初始化安排表甚至重新编译内核。这个体系也使得内核模块(现在称为KLD可以与内核不同时编译、链接、在引导系统时加载，甚至在系统运行时加载。这些操作是通过"内核链接器"(kernel linker)和"链接器集合"(linker set)完成的。链接器集合(Linker Set)是一种链接方法。这种方法将整个程序源文件中静态申明的数据收集到一个可邻近寻址的数据单元中。 SYSINIT要依靠链接器获取遍布整个程序源代码多处申明的静态数据并把它们组成一个彼此相邻的数据块。这种链接方法被称为"链接器集合"(linker set)。SYSINIT使用两个链接器集合以维护两个数据集合，包含每个数据条目的调用顺序、函数、一个会被提交给该函数的数据指针。
