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.
- /usr/share/doc/tiny-initramfs-core/tiny-initramfs.conf.example
- An example configuration file that may be copied to the above location.
