One of the long-missing features of &os; was the ability to + boot up 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, this functionality is known as + pivot_root. The reroot projects provides 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 finished. All the relevant code has been committed + to &os; 11-CURRENT, and is expected to ship with &os; 11.0.
