The previous code discarded entire dependency trees if the first entry in the dependency list compiled by `modprobe --show-depends` is a builtin and otherwise handled its output in a rather hackish way.
depmod looks for files modules.order and modules.builtin which are
generated at kernel build time but were previously not passed to
the modules-shrunk derivation
Pull request #38470 added support for running/building kernels without
modules. This got merged in 38e04bbf29 but
unfortunately while this works perfectly on kernels without modules it
also makes sure that *every* kernel gets no modules.
So all of our VM tests fail since that merge with something like this:
machine# loading module loop...
machine# modprobe: FATAL: Module loop not found in directory /lib/modules/4.14.33
machine# loading module vfat...
machine# modprobe: FATAL: Module vfat not found in directory /lib/modules/4.14.33
machine# loading module nls_cp437...
machine# modprobe: FATAL: Module nls_cp437 not found in directory /lib/modules/4.14.33
machine# loading module nls_iso8859-1...
machine# modprobe: FATAL: Module nls_iso8859-1 not found in directory /lib/modules/4.14.33
machine# loading module fuse...
machine# modprobe: FATAL: Module fuse not found in directory /lib/modules/4.14.33
machine# loading module dm_mod...
machine# modprobe: FATAL: Module dm_mod not found in directory /lib/modules/4.14.33
I shortly tested this against the "misc" VM test and the test is working
again.
In the long term (and I currently don't have time for this) it would be
better to also have a VM test which tests a kernel without modules.

There were conflicting patches of pkgs/os-specific/linux/module-init-tools.
Apparently, the expression was updated independently in both branches. I've
resolved the conflict by preferring the patches from stdenv-updates, because
those patches appeared to be more sophisticated, i.e. they build the manual,
etc.

This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.

tree under $out into a separate stdenv adapter named keepBuildTree.
* makeModulesClosure: support building an initrd for a kernel that has
been compiled with coverage instrumentation.

modules for the initial ramdisk if there were no additional kernel
module packages (such as the NVIDIA driver or AUFS), leading to a
kernel panic in the initrd. This was because in that case modprobe
would print paths referring to the kernel path rather than the
module aggregation path, and then `sed "s^$kernel^$out^"' would
silently fail. Fixed.
* Also, use depmod here rather than doing sed hackery on modules.dep.
* Also, `allowMissing' was broken (missing "$" before the variable
name).
