# Helper for upgrading Linux kernel image and kernel-related modules via APT:
|
||||
# displays list of packages for passing to 'apt-get install' command.
|
||||
#
|
||||
# Works under ordinal account and doesn't requires superuser privileges.
|
||||
#
|
||||
# Requires: apt-cache, egrep, sed, awk, xargs, rpmquery, rpmvercmp
|
||||
#
|
||||
# Uses packages naming conventions from ALTLinux Kernel Policy 1.2.
|
||||
#
|
||||
# Tested on ALTLinux Master 2.4:
|
||||
# kernel-build-tools-0.7-alt1, apt-0.5.15cnc6-alt6,
|
||||
# rpm-4.0.4-alt40, rpm-utils-0.8.1-alt1(rpmvercmp).
|
||||
#
|
||||
# Todo: how to be with kernel-complete package and empty apt-kernel-images list?

$fname0 $version
|
||||
Purpose: Update Linux kernel and installed kernel modules via APT
|
||||
Usage: [VAR=value] $fname0 [options]
|
||||
|
||||
Options:
|
||||
-V, --version Show version string
|
||||
-h, --help Show complete usage
|
||||
-q, --quiet Silent mode (turn off messages)
|
||||
-v, --verbose Detailed mode (turn on messages)
|
||||
-k, --keep Dont remove temporary working directory at finish
|
||||
--debug Enable debugging mode, see below
|
||||
|
||||
Variables for explicit selection of currently installed kernel to be upgraded
|
||||
(by default they are detected automatically via 'uname -r'):
|
||||
KERNEL_FLAVOUR (examples: std-up, vs-smp, ...)
|
||||
KERNEL_VERSION (for example, 2.4.33-std-smp-alt9)
|
||||
|
||||
Debugging mode:
|
||||
Use static data directory instead of temporary,
|
||||
dont overwrite already existing files in data directory
|
||||
(use previously created if they are not removed manually),
|
||||
use more verbose output.
|
||||
|
||||
Examples:
|
||||
sudo apt-get update;
|
||||
export KERNEL_FLAVOUR=std-smp;
|
||||
$fname0 -q | xargs sudo -H apt-get -y install
