NAME

       update-tirfs - generate a tiny-initramfs image

SYNOPSIS

       update-tirfs [-k kernel-version]

DESCRIPTION

       The update-tirfs script generates initramfs images that contains the tiny-initramfs init binary and place
       them  in  the  standard Debian location so that the boot loader may find them. It will call mktirfs(8) to
       create the actual image. When called, all initramfs images in /boot for matching kernel versions will  be
       replaced.

       Please  read /usr/share/doc/tiny-initramfs-core/README.md for an overview of the use cases tiny-initramfs
       was designed for and the features it supports.

OPTIONS

       -k, --kernel-version=kernel-version
              Which kernel version to generate the initramfs image for. By default, the  special  value  all  is
              assumed,  which  indicates that the initramfs image should be regenerated for all installed kernel
              versions.

CONFIGURATION

       If present, the configuration file /etc/tiny-initramfs/tiny-initramfs.conf can  modify  the  behavior  of
       mktirfs(8)  in  how  the initramfs image is constructed. Please refer to the documentation of the mktirfs
       utility for details.

EXAMPLE

       Update all initramfs images:

               update-tirfs

       Update the initramfs image for a specific kernel version:

               update-tirfs -k 4.2.0

DEBIAN MAINTAINER SCRIPTS

       Please do not call this utility from Debian maintainer scripts. Use the update-initramfs trigger instead,
       as that will not depend on the initramfs implementation.

FILES

       /etc/tiny-initramfs/tiny-initramfs.conf
              If present, values in there will be used as defaults for the command line arguments of mktirfs.
