NAME

       installkernel - install a new kernel image

SYNOPSIS

       installkernel version zImage System.map [directory]

DESCRIPTION

       installkernel installs a new kernel image onto the system from the Linux source tree.  It is called by the Linux kernel makefiles when make
       install is invoked there.

       The new kernel is installed into {directory}/vmlinuz-{version}.	If a symbolic link {directory}/vmlinuz already exists, it is refreshed	by
       making a link from {directory}/vmlinuz to the new kernel, and the previously installed kernel is available as {directory}/vmlinuz.old.

BUGS

       installkernel  resides  in  /sbin  only because the Linux kernel makefiles call it from there.  It should really be in /usr/sbin.  It isn't
       needed to boot a system.

NAME

       kernel-install - Add and remove kernel and initramfs images to and from /boot

SYNOPSIS

       kernel-install COMMAND KERNEL-VERSION [KERNEL-IMAGE]

DESCRIPTION

       kernel-install is used to install and remove kernel and initramfs images to and from /boot.

       kernel-install will execute the files located in the directory /usr/lib/kernel/install.d/ and the local administration directory
       /etc/kernel/install.d/. All files are collectively sorted and executed in lexical order, regardless of the directory in which they live.
       However, files with identical filenames replace each other. Files in /etc/kernel/install.d/ take precedence over files with the same name
       in /usr/lib/kernel/install.d/. This can be used to override a system-supplied executables with a local file if needed; a symbolic link in
       /etc/kernel/install.d/ with the same name as an executable in /usr/lib/kernel/install.d/, pointing to /dev/null, disables the executable
       entirely. Executables must have the extension ".install"; other extensions are ignored.

COMMANDS

       The following commands are understood:

       add KERNEL-VERSION KERNEL-IMAGE
	   kernel-install creates the directory /boot/MACHINE-ID/KERNEL-VERSION/ and calls every executable /usr/lib/kernel/install.d/*.install
	   and /etc/kernel/install.d/*.install with the arguments

	       add KERNEL-VERSION /boot/MACHINE-ID/KERNEL-VERSION/

	   The kernel-install plugin 50-depmod.install runs depmod for the KERNEL-VERSION.

	   The kernel-install plugin 90-loaderentry.install copies KERNEL-IMAGE to /boot/MACHINE-ID/KERNEL-VERSION/linux. It also creates a boot
	   loader entry according to the boot loader specification in /boot/loader/entries/MACHINE-ID-KERNEL-VERSION.conf. The title of the entry
	   is the PRETTY_NAME parameter specified in /etc/os-release, or "Linux KERNEL-VERSION", if unset. If the file initrd is found next to the
	   linux file, the initrd will be added to the configuration.

       remove KERNEL-VERSION
	   Calls every executable /usr/lib/kernel/install.d/*.install and /etc/kernel/install.d/*.install with the arguments

	       remove KERNEL-VERSION /boot/MACHINE-ID/KERNEL-VERSION/

	   kernel-install removes the entire directory /boot/MACHINE-ID/KERNEL-VERSION/ afterwards.

	   The kernel-install plugin 90-loaderentry.install removes the file /boot/loader/entries/MACHINE-ID-KERNEL-VERSION.conf.

EXIT STATUS

       If every executable returns with 0, 0 is returned, a non-zero failure code otherwise.

FILES

       /usr/lib/kernel/install.d/*.install /etc/kernel/install.d/*.install
	   Drop-in files which are executed by kernel-install.

       /etc/kernel/cmdline /proc/cmdline
	   The content of the file /etc/kernel/cmdline specifies the kernel command line to use. If that file does not exist, /proc/cmdline is
	   used.

       /etc/machine-id
	   The content of the file specifies the machine identification MACHINE-ID.

       /etc/os-release
	   The content of the file specifies the operating system title PRETTY_NAME.
