dracut is the tool used by desktop distributions to build initrds. In the embedded world, it can be very usefull, too, for instance when wanting to create an initramfs for a system recovery mode. Whereas it is definitively possible to achieve this with buildroot, the process is to have a dedicated buildroot configuration for that, and perform a full build. Instead of doing that, the idea is to use dracut to pick the needed binaries/shared libraries, configuration files, or kernel modules from the 'target' directory. The advantage is to save build time, and also to have a consistency between the packages versions taken for the recovery and the production filesystem.
