mkinitcpio will always create /lib/modules/$kernver/kernel in the image,
so we can use this to detect the kernel the image was built for, even if
the image contains no modules.

This increases compression efficiency, which might be useful on an image
containing a lot of modules.
For the usecase I had in mind, this reduced the size by about a quarter.

depmod doesn't care where modules are, within reason, and separating
modules into the respective hierarchies only serves to irritate users
who go looking for modules in the rootfs (aka me). Forget all this and
dump everything into the kernel/ dir.

Move the unsetting of the errtrace and ERR trap flags to after the
image has been built. This lets us capture errors during module
installation to the build root and the call to depmod. Either of these
steps failing could be hazardous and should prompt a failure.

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.

Move this logic inside fsck_device as well, so that fastboot skips a
possible fsck on the /usr partition as well.

our fsck_ret function would always return true when passed 0, which
clearly isn't what we want. Use a simple string compare instead.

An error in logic here would cause the --try flag to be passed to all

udev does not support this as of udev-176, so there is no point in
pretending it will work.
This also drops devtmpfs_mounted=1, so any custom hooks that use this
would have to be updated (no official hooks are affected).

This is cosmetic change, but using rootfs is more correct than ramfs.

Use findmnt to detect the existance of a separate /usr partition
existing in the real root. If it does exist, fetch the options for it
and mount it. This currently makes a lot of assumptions and won't be
very friendly towards something such as a dm-crypt device.

This is required for mounting a separate /usr. While the shutdown hook
is essentially a soft requirement for a separate /usr, we shouldn't

Refer to commit 9a9e0d68555 in the kernel where Linus removes this and

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.

When present, modules.order will allow depmod to order the binary module
indicies for faster lookups and more deterministic behavior in resolving
aliases. We can discard this file from the buildroot after depmod is
called.
modules.builtin.bin is added as well (generated from modules.builtin),
to allow modprobe to not fail when a symbol is provided as a builtin.

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.

Since we now silently overwrite instead of silently failing on existing
files and symlinks, we have a lot of sodeps which are overwritten by
various binaries -- udevd and udevadm being one example. Nip this in
add_binary by doing our own check and preventing addition of
pre-existing files in the $BUILDROOT.

This goes in hand with an earlier commit which changed behavior to
silenltly overwrite files rather than silently fail.
Signed-off-by: Dave Reisner <dreisner@archlinux.org>

Now we fail silently if the file exists, which means there is no easy way to overwrite binaries.
I think it makes the most sense to do the following:
1) add all the busybox stuff as a basic system;
2) overwrite some of the links with any binaries we add to base hook;
3) allow users to write their own hooks to overwrite even more stuff.
This can now be done by this hook.
v2: make sure we are able to overwrite a symlink pointing to a directory

Maybe something went wrong with depmod after a kernel install, or the
user grabbed a kernel directory for an old kernel. Either way, if you're
using an initramfs, there's a very high probability that you'll have at
least 1 module on it.
