- Generate a link to the initramfs file with an appropriate file
extension, guessed based on the compressor by default
- Use correct metadata in u-boot images if generated, up to now this
was hardcoded to gzip and would silently generate an erroneous image
if another compressor was specified
- Document all the parameters
- Improve cross-building compatibility, by allowing passing either a
string as before, or a function taking a package set and returning the
path to a compressor in the "compressor" argument of the
function.
- Support more compression algorithms
- Place compressor executable function and arguments in passthru, for
reuse when appending initramfses

Before this commit, the firmware information would be loaded from the
currently running kernel, not from the kernel to be loaded.
This commit ensures the correct kernel version and modules are read.
After a recent upgrade of modinfo, its output is now incorrect for
builtin modules. This commit filters out the output until a fix is made
available upstream
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
not all valid file names are valid derivation names. This can cause
troubles when, for example, trying to place systemd template unit
files, which contain an '@' in their name, in an initrd.
Fixes#53987
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.

Resolved the following conflicts (by carefully applying patches from the both
branches since the fork point):
pkgs/development/libraries/epoxy/default.nix
pkgs/development/libraries/gtk+/3.x.nix
pkgs/development/python-modules/asgiref/default.nix
pkgs/development/python-modules/daphne/default.nix
pkgs/os-specific/linux/systemd/default.nix
For a while now, the only thing the 'uboot' attribute does is to tell
whether to add ubootTools to kernel/initrd builds. That can be
determined with platform.kernelTarget == "uImage" just as well.
To achieve reproducible results, `cpio` archive members are added in
sorted order and inodes renumbered.
The `cpio-clean.pl` script is made obsolete by setting mtimes via
`touch` & using `cpio --reproducible`. Suggested by @dezgeg in
https://github.com/NixOS/nixpkgs/pull/21273#issuecomment-268116605.
Note that using `--reproducible` means that initial ramdisk creation now
requires at least `cpio` version 2.12 (released in 2015).
See the comments at f67015cae4
for more information.
Please note: this makes initrd unrepeatable again, but most people will prefer that above an unbootable system.

Merge conflicts seemed trivial, but a look from viric and aszlig would be nice.
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.

I introduce the new nixpkgs parameter "platform", defaulting to "pc",
which was before defined as an attribute of nixpkgs.
I made the crossSystem nixpkgs attribute set parameter contain its own 'platform'.
This allows cross-building a kernel for a given crossSystem.platform in a non-PC
platform.
The actual native platform can be taken from stdenv.platform, and this way we also
avoid the constant passing of 'platform' to packages for platform-dependant builds
(kernel, initrd, ...).
I will update nixos accordingly to these changes, for non-PC platforms to work.
I think we are gaining on flexibility and clearness. I could cross build succesfully
an ultrasparc kernel and a mipsel kernel on PC. But since this change, I should be able
to do this also in non-PC.
Before this change, there was no possibility of distinguishing the "target platform" or
the "native build platform" when cross building, being the single "platform" attribute
always interpreted as target platform.
The platform is a quite relevant attribute set, as it determines the linuxHeaders used
(in the case, by now the only one supported, of linux targets).
The platform attributes are quite linux centric still. Let's hope for more generality to come.
