dracut is an event driven initramfs infrastructure.

dracut (the tool) is used to create an initramfs image by copying tools

and files from an installed system and combining it with the

dracut framework, usually found in /usr/lib/dracut/modules.d.

Unlike other implementations, dracut hard-codes as little

as possible into the initramfs. The initramfs has

(basically) one purpose in life -- getting the rootfs mounted so that

we can transition to the real rootfs.  This is all driven off of

device availability.  Therefore, instead of scripts hard-coded to do

various things, we depend on udev to create device nodes for us and

then when we have the rootfs's device node, we mount and carry on.

This helps to keep the time required in the initramfs as little as

possible so that things like a 5 second boot aren't made impossible as

a result of the very existence of an initramfs.

Most of the initramfs generation functionality in dracut is provided by a bunch

of generator modules that are sourced by the main dracut script to install

specific functionality into the initramfs.  They live in the modules.d

subdirectory, and use functionality provided by dracut-functions to do their

work.
