What does Mkinitrd do in Linux?
mkinitrd creates an initial image used by the kernel for preloading the block device modules (such as IDE, SCSI or RAID) which are needed to access the root filesystem. mkinitrd automatically loads filesystem modules (such as ext3 and jbd), IDE modules, all scsi_hostadapter entries in /etc/modprobe.
What is the kernel function used to load a module?
To load a kernel module, we can use the insmod (insert module) command.
What is dracut mode Linux?
Dracut is a set of tools that provide enhanced functionality for automating the Linux boot process. The tool named dracut is used to create a Linux boot image (initramfs) by copying tools and files from an installed system and combining it with the Dracut framework, which is usually found in /usr/lib/dracut/modules.
Where do I load the modules in mkinitrd?
Load the modules module in the initial ramdisk image. The module gets loaded after any SCSI modules which are specified in /etc/modprobe.conf. This option may be used as many times as necessary. Force adding kernel integrity checking to the created initrd. Specifies SCSI modules to be loaded and module options to be used.
What is the purpose of mkinitrd in Linux?
mkinitrd creates an initial image used by the kernel for preloading the block device modules (such as IDE, SCSI or RAID) which are needed to access the root filesystem.
How are kernel modules loaded in the initrd?
The RAM disk/kernel image used to boot up Linux holds the initial modules that are used to get the system up; after the initial boot other modules are loaded as needed. In some cases, the kernel modules need to be included in the RAM disk. Examples would include the Fibre Channel Cards, disk controllers and file-system drivers.
Where does the mkinitrd run in an image?
Load the module module in the initial ramdisk image. The module gets loaded before any SCSI modules which are specified in /etc/modprobe.conf . This option may be used as many times as necessary. Prints out verbose information while creating the image (normally the mkinitrd runs silently).
