initramfs造句

• Unlike existing initramfses, dracut's framework attempts to have as little hard-coded into the initramfs as possible.
• The initramfs has ( basically ) one purpose in life mounting the root file system so the boot process can transition to the real rootfs.
• Most of the initramfs generation functionality in dracut is provided by generator modules that are sourced by the main dracut tool to install specific functionality into the initramfs.
• Most of the initramfs generation functionality in dracut is provided by generator modules that are sourced by the main dracut tool to install specific functionality into the initramfs.
• However, one can choose to use a custom kernel configuration and use genkernel to compile it, and still benefit from other features such as the initramfs builder.
• Genkernel compiles the kernel with all available device drivers built as full disk encryption make usage of an initramfs unavoidable; here genkernel can save the user from manually creating one.
• This feature is implemented in live-initramfs and allows the user to run a live distro that does not run from ram by default by adding toram to the kernel boot parameters.
• This helps to keep the time required in initramfs down so that things like a 5-second boot are not made impossible as a result of the very existence of an initramfs.
• This helps to keep the time required in initramfs down so that things like a 5-second boot are not made impossible as a result of the very existence of an initramfs.
• For some applications, initramfs can use the " casper " utility to create a writable environment using unionfs to overlay a persistence layer over a read-only root filesystem image.
• At the end of its boot sequence, the kernel tries to determine the format of the image from its first few blocks of data, which can lead either to the initrd or initramfs scheme.
• Regardless of the selected installation type, further actions need to be taken before the new system is ready for use, most notably by installing a bootloader, creating an initramfs, and configuring the new system.
• With more recent bootloaders it is possible to load the MD support as a kernel module through the initramfs mechanism, this approach allows you to let the / boot filesystem be inside any RAID system without the need of a complex manual configuration.
• "' Harald Hoyer "'is a computer programmer and photographer, best known for developing the dracut initramfs generator and framework, the udev device manager of Linux, Harald Hoyer also made various contributions to the Linux Kernel, starting 1997.
• Therefore, instead of having hard-coded scripts to do various things, dracut's initramfs depends on udev to create symbolic links to device nodes and when the rootfs's device node appears, it mounts it and switches root to it.
• The initramfs is one solution to the " chicken or the egg " problem of some mass storage devices and some file systemsespecially cryptographic file systemsrequiring complex device drivers to read data from them, when device drivers are normally stored inside the file system in the mass storage device.
• initramfs, also known as " early user space ", has been available since version 2.5 . 46 of the Linux kernel, with the intent to replace as many functions as possible that previously the kernel would have performed during the start-up process.
