+ Add and remove kernel and initramfs images to and from /boot
+
+
+
+
+ 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 directories in
+ which they live. However, files with identical file names 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>
+
+ 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>/"
+
+ kernel-install copies <KERNEL IMAGE> to
+ /boot/<MACHINE-ID>/<KERNEL VERSION>/linux.
+
+ kernel-install also creates a boot loader entry according to the boot loader specification
+ in /boot/loader/entries/<OS-ID>-<KERNEL VERSION>-<MACHINE-ID>.conf.
+ If the file initrd is found next to the linux file,
+ the initrd will be added to the configuration.
+
+
+
+ remove <KERNEL VERSION> <KERNEL IMAGE>
+ 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>/
+ and the file /boot/loader/entries/<OS-ID>-<KERNEL VERSION>-<MACHINE-ID>.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.
