On compressed images, bash 4.3 gets salty:
$ lsinitcpio initrd.gz >/dev/null
/usr/bin/lsinitcpio: line 78: warning: command substitution: ignored null byte in input
/usr/bin/lsinitcpio: line 90: warning: command substitution: ignored null byte in input
Tidy up all of our hexdump comparisons via command substitution to use
process substitution instead.

crc32 is a builtin module in the Arch kernel but also a crypto module.
Resolve by this only noting that a module is added if the value in the
has is 1, and not 2 (indicating a builtin).
While we're here, change the f2fs softdep of crc32 to crypto-crc32.

this is no longer needed -- we get softdeps from the kernel.

systemd v232 only activates systemd-vconsole-setup via udev. Follow this
to make sure things work properly. This also obsoletes the modules-load
hack.

This really ought to be fixed in the module, but here we are again
guessing at module requirements.

builderrors -> _builderrors -- this makes binary dep resolution
properly a builderror. As seen in:

Arch's binaries are all in /usr/bin, so let's not bother searching in
duplicates of this directory.

It's been too long and I've forgotten how to hack on mkinitcpio...
|

...and mine too, now that he points it out.

These were curiously omitted from the documentation.

If the MODULES contain a GPU driver like i915, wait for it
to be loaded. This avoids the font configuration being lost.

Arch might not really support some of these, but mkinitcpio can.

This prevents having unquoted expansion in the bsdcpio commandline

This refactors parse_cmdline into a few chunks of code, mainly to
separate the work of parsing from the handling of the actual parsed
parameters. By default, parse_cmdline_item is used as the callback for
handling the parameters, but this could be overriden by other code
sourcing init_functions if desirable.
Our test harness passes more tests, but we leave behind some expected
failures to describe the cases where it still fails. Fortunately I've
not yet been able to find any cases which warrant --expect-parse-fail.
|
|
Some of these tests currently fail including hard failures where the
shell quits entirely (this would lead to a kernel panic). A followup
commit will rewrite the parse_cmdline function to improve it and fix
these deficiencies.

Version extraction only works on x86 (i686 and x86_64) kernels.

rootfstype is handled by the kernel, so we should handle it, too.

This is true of more and more modules with the advent of aliases, e.g.
$ modinfo -F filename crc32c
/lib/modules/4.6.2-rampage/kernel/arch/x86/crypto/crc32c-intel.ko.gz
/lib/modules/4.6.2-rampage/kernel/crypto/crc32c_generic.ko.gz

modinfo outputs softdeps which we can add if they exist (failing
quietly on not-found). this obviates the need for some of our own
module quirks.
The output of modinfo can take many forms, as it's nearly freeform text
in the .modinfo section of the kernel module. The basic form is:
softdep: pre: foo
But it might also be:
softdep: pre: foo bar post: baz
Or:
softdep: pre: foo
softdep: post: bar
So just parse the entire line, discarding anything that ends with a ':'.

Not that it really matters, but let's scope this to where we actually
care for the modified time output.

The archive goes from looking like this:
.
./buildconfig
./config
./init
./init_functions
./VERSION
./lib64
./sbin
To:
buildconfig
config
init
init_functions
VERSION
lib64
sbin
Note the lack of the "root" entry and leading "./". This fixes an issue
with packing ucode into the initramfs since the kernel really wants an
exact match, and not path equivalency.

This hook adds host-specific configuration to the image. Currently,
it adds the hostname and machine-id files for usage with journald.

This patch adds in some extra hackery to make sure that users with btrfs
root filesystems don't end up with unusable initrds due to the following
change made upstream [1]. TL;DR: The btrfs module has dropped it's
libcrc32c dependency, so mkinitcpio no longer pulls in the crc32c module
necessary for the btrfs module to be inserted. The crc32c module was
only pulled in previously due to mkinitcpio hackery [2], so extra
hackery now seems like the logical path.
This problem can be experienced by using linux-mainline on an Arch
machine with a btrfs root filesystem. Besides from this extra hackery,
an alternative workaround would be for users in this situation to add
crc32c to their MODULES aray in their mkintcpio.conf. Of course, this
needs to be done ahead of the linux-3.14 upgrade for them to avoid the
problem (assuming none of their other modules depend on libcrc32c).

Prevents problems with bogusly named filesystems, e.g.:

Should have been removed as part of previous commit, as this was
clearly just a typo.

This isn't documented, but it's needed since the kernel lz4 support is
based on the original streaming format and not the newer default. Use
-l to force the legacy codec.
Fixup lsinitcpio to support the older format, and, add a warning when
the newer format is detected. Who knows when this will be "resolved" ...

This hook works together with the systemd hook from the systemd
package and requires the add_systemd_unit function.
It launches systemd-vconsole-setup.service in initramfs
and is especially useful to unlock encrypted volumes in
initramfs.
|
|
Pretty much everyone benefits from this service, as it is always better than
having no shutdown-ramfs. If someone puts their own shutdown-ramfs in place,
it will likely be done by initramfs and this service will be skipped
automatically.
In more obscure situations, it can still be masked.
