This makes us a little more future proof as far as moving files around.
No need for 2 lib/ directories in early userspace anyways.

Everything we need to know about the devices is already in sysfs
attributes for the md devices. Read any found nodes for raid levels and
sort them into our whitelist. This removes the need for root in order to
"scan" arrays.
More code churn on top of d11ba00.

Since 3b18c9cd we have a blank /etc/fstab in the image. This is also
forward thinking for the next release of util-linux (2.22), where fsck
complains loudly about my filthy hack of using /dev/null as /etc/fstab.

sysfs contains enough information about block devices to be able to
determine the order of stacked devices such as lvm, raid, or crypto. By
looking at the device symlinks from the holders/ attributes of a block
device, we can walk down each device chain until we reach the most
descendant device.
For each of these devices at the end of a chain, detect its type and
perform the appropriate action to disassemble it. Then, walk back up the
device chain, disassembling each parent device.
To save ourselves some pain and make sure we're fairly accurate, lsblk
is brought in for detection of device types.

This is implemented for the keymap and consolefont hooks. It's done in
such a way that vconsole.conf and locale.conf will override and
supplement rc.conf.
Implements FS#29022.

This is a really ugly patch, but allows mkinitcpio to read hooks from
multiple locations, namely:
/usr/lib/initcpio/{install,hooks}
/lib/initcpio/{install,hooks}
Preference is given to the first, and all files included with mkinitcpio
are moved there.

detected, add the fsck.ext4 binary and add symlinks.

Trading out modinfo for modprobe allows us to detect filesystems like
ext2 and ext3 which might be aliased to ext4 in the case of Kconfig
CONFIG_EXT4_USE_FOR_EXT23 being enabled. Maybe this catches other insane
corner cases, too.
Since we now treat this as possible aliases, we also need to be mindful
of the fact that it could resolve to multiple module names. Assign the
output as an array to respect this.
Fixes FS#28569.

FS#10061 still isn't dead, its just resting:
https://bbs.archlinux.org/viewtopic.php?pid=1056003
An strace from a helpful user shows that our mdadm call is trying to
open a block device and the call never returns:
open("/dev/sdb", O_RDONLY|O_DIRECT|O_LARGEFILE
Fix this by only scanning explicitly the block devices we're interested
in, found via sysfs. This is an all around win for everyone, especially
users who have mdadm installed without any need for it.
This changes some of our assumptions about the environment:
- the mdadm binary exists when we find md devices in /sys
- the user running mkinitcpio isn't any specific UID or part of any
particular group, but merely has read access to the block devices
we're about to scan.

Refer to commit 9a9e0d68555 in the kernel where Linus removes this and
says "to be revisited later". The only option (currently) is to built
this into your kernel image.

This adds functionality to pivot to back to the initramfs on shutdown,
thereby allowing the system to unmount the real root device. This will
be necessary for anyone with /usr as a separate partition.

This means that no "setup" of the initramfs is requried on boot,
and this should make testing a lot eaiser by just chrooting into
the ramfs to check if it works.

Add compat symlinks from /bin, /sbin and /usr/sbin, so nothing is lost.
This will make sure that it is not possibly to install two different
versions of the same binary in PATH.
The main usecase of this is that we want to be able to override any
symlink provided by busybox by adding a binary by the same name. With
this patch we don't have to worry in case the busybox symlink and the
binary we add are in different directories; the last binary to be added
always takes precedence.

* ipconfig cmd writes a file in /tmp that is ready for direct evaluation.
We can use this instead of parsing the output, to do this some variable
renames are needed.
* Add /tmp as part of "base" layout since this can be used by others hooks/cmds.

Providing this means we no longer need blkid for FS detection, as mount
will do this for us. Adds a slight bloat to the image, in exchange for a
huge convenience. Messaging is changed to assume that /bin/mount will
provide useful feedback for us on failure.

cc36db45 was a bit too strict about localizing variables and blew out
TMPDIR, which might be a legit variable sourced from the calling

writeable before proceeding.

We conditionally, but naively, add modules in some of our install hooks,
but the kernel may not have these. Note that these modules can fail
silently by detecting a '?' suffix on the module name. In conjunction with
this, the add_module function now takes a flag, -t or --try, which will
ignore module not found errors from modinfo. The config file will also
support this syntax.

This is partially in response to FS#24685, which should hopefully cut
