One of the long missing features of &os; was the ability to + boot with a temporary rootfs, configure the kernel to be able + to access the real rootfs, and then replace the temporary root + with the real one. In Linux, the functionality is known as + pivot_root. The reroot projects aims to provide + similar functionality in a different, slightly more + user-friendly way: rerooting. Simply put, from the user point + of view it looks like the system performs a partial shutdown, + killing all processes and unmounting the rootfs, and then + partial bringup, mounting the new rootfs, running init, and + running the startup scripts as usual.

+ +

The project is in the late implementation phase. A working + prototype was written, and work is in process to rewrite it in + an architecturally nicer way.
