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.
Suggested by FS#27906.

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.

Avoiding adding a filesystem module to the whitelist when it doesn't
actually exist as a module (in case its compiled in staticly).

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.

This is mainly for avoid this:
[ramfs /]# mount /dev/md0 /mnt/a
[ramfs /]# mount -o bind /mnt/a /mnt/b
[ramfs /]# mount -o bind,remount,ro /mnt/b
warning: can't open /etc/fstab: No such file or directory
[ramfs /]#

* 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.

This is a much better solution than busybox's, as it will move our API

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
environment. Restore this behavior with a bit of refactoring, and
additionally add in a check to make sure the temporary directory is
writeable before proceeding.
Fixes FS#26373.

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.

No logical code changes -- this is purely a syntactical cleanup and
standardization across the build hooks along with ensuring that help
messages are wrapped to 80 columns or less. All hooks get the same
treatment, adhering to the following style:
#!/bin/bash
build() {
COMMANDS
}
help() {
cat <<HELPEOF
This is a help message.

This is partially in response to FS#24685, which should hopefully cut
back on configuration duplication on non-sysvinit systems. This does,
however, also fix a bug with keymap/consolefont pulling the wrong
rc.conf when BASEDIR is not '/' or unset.

We can't let add_file get its hands on the config file, because we need
to be sure that an absolute path is honored. As a side effect, ensure
that $BASEDIR is appended to the config file during preset processing.

Bashify and refactor to cut back on unnecessary churn. Since our
{all,checked}_modules functions always return clean module names, we can
add these directly to the autodetect file instead of aggregating them
during the autodetect hook and then cleansing one at a time. There's a
small speed increase here for the simplest code path.

* Create only the directories that are necessary. If others are

Output style and coloring is borrowed from makepkg with minor
adjustments. Most instances where we encounter fatal errors are replaced
with a 'die' function to wrap this up neatly. In addition, we introduce
the -n flag, for no-color.
As a side effect, we need to source the functions file earlier so we
have the output functions available earlier.

This was only ever used in the base layout, and it's not needed.
devices will be present if we're using devtmpfs, and created for us by
init if we mount on tmpfs.
Also, this is part of our move towards using bsdcpio instead of
gen_init_cpio, and as a side effect we can no longer support this. Any
devices that need to be created should be done so by the runtime hooks,
not the install time hooks.
