Some systems use the dracut package to create an initramfs image. [6] In the initramfs scheme, the kernel executes /init as its first process that is not expected to exit. [ 5 ] 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 ...
Many distributions use dracut to generate and maintain the initramfs image. The root file system is later switched via a call to pivot_root() which unmounts the temporary root file system and replaces it with the use of the real one, once the latter is accessible. [14] The memory used by the temporary root file system is then reclaimed.
Unlike existing Linux boot images, the Dracut framework attempts to introduce as little hard-coded logic into the initramfs as possible. [1] The initramfs has essentially one purpose: locating and mounting the real root file system so that the boot process can transition to it. [1] This functionality is dependent on device availability. [1]

It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.
