kexecbin

Documentation

Overview

Package kexecbin offers a kexec API via a callout to kexec-tools.

u-root's kexec implementation currently covers less use-cases than the one from kexec-tools. The user has to embed a kexecbin program in the initramfs, and make it available in the PATH, then call the `KexecBin` function. Please note that adding an external kexec implementation will increase the ramfs size more than the pure-Go implementation from u-root.
