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.
