#
# Every kernel module has a flag 'supported'. If this flag is not set loading
# this module will taint your kernel. You will not get much help with a kernel
# problem if your kernel is marked as tainted. In this case you firstly have
# to avoid loading of unsupported modules.
#
# Setting allow_unsupported_modules 1 enables loading of unsupported modules
# by modprobe, setting allow_unsupported_modules 0 disables it. This can
# be overriden using the --allow-unsupported-modules commandline switch.

##############################################################################
# How it works:
# * Kernels install modules below /lib/modules/$krel/kernel/.
# * KMPs install modules below /lib/modules/$krel/updates/ or .../extra/.
# * Symbolic links to modules of compatible KMPs are created under
# /lib/modules/$krel/weak-updates/{updates,extra}/... (the original path
# below /lib/modules/$other_krel is used).
# * Depmod searches the directories in this order: updates/, extra/,
# weak-updates/, kernel/ (see /etd/depmod.conf or
# /etc/depmod.d/00-system.conf for details).
# * Compatibility of a kernel with a KMP is defined as: The KMP is built
# for the same flavor as the kernel and after adding the KMP modules to
# the kernel, depmod -e -E Module.symvers reports no errors about
# missing symbols or different symbol checksums. See the
# has_unresolved_symbols() function for details.
#
# * At KMP install time (function add_kmp()), we create symbolic links
# for all kernels that this KMP is compatible with. We skip kernels that
# already contain symbolic links to a newer KMP of the same name,
# contain the KMP itself or another version in updates/ or extra/ or
# have overlapping module names with other KMPs in the respective
# kernel (this should not happen).
# * At kernel install time (functions add_kernel()), we create symbolic
# links for each compatible KMP, unless the KMP or a different one with
# overlapping module names is present in updates/ or extra/ (KMP build
# against $krel can be installed before a kernel with that version).
# When multiple KMPs of the same name are compatbile, we chose the one
# with the highest version number. This is repeated when subsequent
# subpackages (main or -extra) of that kernel are installed.
# * At KMP removal time (function remove_kmp()), the modules and their
# symlinks are removed and, where possible, replaced by symlinks to the
# newest of the remaining compatible version of that KMP.
# * [NOT IMPLEMENTED] When a kernel subpackage is removed, symlinks to
# KMPs that become incompatible are removed as well. This is not
# implemented, because removing the main subpackage and only keeping
# the -base package AND having KMPs installed is not an expected
# scenario, and implementing this would only slow down kernel updates.
# * When the kernel is removed (function remove_kernel()), it's
# weak-updates directory is also removed.
#
# naming conventions used in this script:
# $kmp: name-version-release of a kmp, e.g kqemu-kmp-default-1.3.0pre11_2.6.25.16_0.1-7.1
# $kmpshort: name of a kmp, e.g kqemu-kmp-default
# $basename: portion of $kmp up to the "-kmp-" part, e.g kqemu
# $flavor: flavor of a kmp or kernel, e.g default
# $krel: kernel version, as in /lib/modules/$krel
# $module: full path to a module below updates/
# $symlink: full path to a module symlink below weak-updates/
#
# files in $tmpdir:
# krel-$kmp: kernel version for which $kmp was built
# modules-$kmp: list of modules in $kmp (full paths)
# basenames-$kmp: list of basenames of modules in $kmp
# kmps: list of kmps, newest first
