RHBA-2018:0807 - Bug Fix Advisory

Topic

An update for kexec-tools is now available for Red Hat Enterprise Linux 7.

Description

The kexec-tools packages contain the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel.

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.5 Release Notes linked from the References section.

Users of kexec-tools are advised to upgrade to these updated packages.
