Kexec is a system call that enables loading and booting into another kernel. This is useful for fast reboots that skip the BIOS or UEFI initialisation process.
On a typical Alpine setup, it can be used via:
# kexec -l /boot/vmlinuz-edge --initrd /boot/initramfs-edge --reuse-cmdline # kexec -e
There are no Alpine-specific considerations for Kexec. Please review the man page and existing references below of more details. This page is deliberately kept short in order to avoid duplicating existing documentation.
