**What is Dracut?**
Dracut is *a set of tools which provide enhanced functionality for automating the Linux boot process.*
> **What does the `dracut` tool do?**
> The `dracut` tool *creates a Linux boot image (initramfs).*
>
> **How does the `dracut` tool create an initramfs?**
> The `dracut` tool creates an initramfs *by copying tools and files from an installed system to combine them with the Dracut framework.*
> > **Where is the Dracut framework stored?**
> > The Dracut framework is stored *in `/usr/lib/dracut/modules.d`.*
**What does the Dracut framework attempt to introduce into the initramfs?**
The Dracut framework attempts to introduce into the initramfs *as little hard-coded logic as possible.*
> **What is the purpose of the initramfs and why?**
> The purpose of the initramfs is *to locate and mount the real root file system so the boot process can transition to it.*
> > **What is the ability of the initramfs to locate and mount the real root file system dependent on?**
> > The ability of the initramfs to locate and mount the real root file system is dependent on *device availability.*
> >
> > **What does Dracut's initramfs not depend on to determine device availability and suitability?**
> > To determine device availability and suitability, Dracut's initramfs doesn't depend on *hard-coded scripts.*
> > > **What does Dracut's initramfs depend on to determine device availability and suitability?**
> > > To determine device availability and suitability, Dracut's initramfs depends on *the Linux device manager, udev, to create symbolic links to device nodes.*
> >
> > **What does Dracut do when the root file system's device node appears?**
> > When the root file system's node appears, Dracut *mounts it as the new root file system.*
> > > **What does the process of mounting the root file system's device node as soon as it appears help to minimize?**
> > > Mounting the root file system's device node as soon as it appears helps to minimize *the time required in the initramfs.*
**What is most of the initramfs generation functionality in Dracut provided by?**
Most of the initramfs generation functionality in Dracut is provided by *generator modules sourced by the main `dracut` tool.*
> **What do the generator modules sourced by the main `dracut` tool do?**
> The generator modules sourced by the main `dracut` tool *install specific functionality into the initramfs.*
**What filesystems does Dracut support booting from?**
The filesystems Dracut supports booting from include:
* ext2.
* ext3.
* ext4.
* btrfs.
* ISO_9660.
* DM RAID.
* MD RAID.
* LVM2.
* Device mapper multipath I/O.
* dm-crypt.
* cifs.
* FCoE.
* iSCSI.
* NBD.
* NFS.
