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
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.
Real-time Java is a catch-all term for a combination of technologies that enables programmers to write programs that meet the demands of real-time systems in the Java programming language.

The Spring Framework is an application framework and inversion of control container for the Java platform. [2] The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform.
Other possible types of questions that may be asked alongside structured interview questions or in a separate interview include background questions, job knowledge questions, and puzzle-type questions. A brief explanation of each follows. Background questions include a focus on work experience, education, and other qualifications. [68]
