PROGRAM:

NAME

ketchup - Utility to update the kernel source

SYNOPSIS

ketchup [options] <ver>

DESCRIPTION

This tool synchronises a local kernel tree with a desired kernel version and patch set
from a kernel.org mirror. The default requires a GPG key on your keyring, to verify the
identity of the patches and source archives. Entire kernel images are not downloaded
unless necessary, so bandwidth is saved. Patches are applied and removed as necessary to
attain the requested version.

OPTIONS

-a --archive (~/.ketchup)

cache directory

-d --directory (.)

directory to update

-f --full-tarball

if unpacking a tarball, download the latest

-g --gpg-path (/usr/bin/gpg)

path for GnuPG

-G --no-gpg

disable GPG signature verification

-k --kernel-url (http://www.kernel.org/pub/linux/kernel)

base url for kernel.org mirror

-l --list-trees

list supported trees

-m --show-makefile

output version in makefile <arg>

-n --dry-run

don't download or apply patches

-o --only-dl

don't apply patches

-p --show-previous

output version previous to <arg>

-q --quiet

reduce output

-r --rename-directory

rename updated directory to linux-<v>

-s --show-latest

output the latest version of <arg>

-u --show-url

output URL for <arg>

-w --wget (/usr/bin/wget)

command to use for wget

CONFIGURATION

Ketchup will read files named .ketchuprc in $HOME and in the target kernel directory, with
the kernel directory taking precedence.

A .ketchuprc file uses the Python syntax and may set the following variables:

default_tree

The default_tree option specifies the kernel version to work with if one is not
given on the command line.

precommand

The precommand option specifies a command to run before synchronising the kernel
tree to the required version.

postcommand

The postcommand option specifies a command to run after synchronising the kernel
tree to the required version.
