e1ebae700a fs/common: Create initial console device
A /dev/console node must be present in rootfs when the Linux kernel
boots otherwise the kernel will print the following warning:
"Warning: unable to open an initial console"

This is because when we use an initramfs the /dev directory is not
populated at this point. This can cause problems when a program
(e.g ldso with early debugging enabled) opens a standard file
descriptor for read/write before these descriptors are actually
created by the init process later on.

9226a9907c Warn the user about the usage of output/target as the root filesystem
A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.

This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:

 * At the beginning of the build, right after the skeleton has been
   copied, support/misc/target-dir-warning.txt is copied to
   output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM

 * In the filesystem images creation code, this file is removed before
   launching fakeroot, and restored right after that, so that this
   file is not present in the generated root filesystem images.

Note that the file has not been added to the default skeleton for two
reasons:

 * It would have annoying to have in our source tree a file named in
   capital letters inside system/skeleton/

 * The proposed way works even if the user uses a custom skeleton.

ff3391323a iso9660 fs: use cpio initrd instead of ext2
The ext2 initrd is pretty broken, because it requires an additional
root=/dev/ram0 command line parameter, and a /init to mount
devtmps that isn't there in out ext2 rootfs.  So just use a cpio
instead.

Note that there is no check if the kernel supports initramfs or the
selected compression method.

Also removed a bit of dead code in iso9660.mk.

6c3e3ad419 New top-level directory: system
This directory groups the following elements:
 * the default root filesystem skeleton
 * the default device tables
 * the Config.in options for system configuration (UART port for
   getty, system hostname, etc.)
 * the make rules to apply the system configuration options

Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.

As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.

4ef7ec585c Remove unused .fakeroot.* mechanism
There used to be a mechanism using which packages could leave a
.fakeroot.<something> file which could contain commands to be executed
within the fakeroot environment. Since this mechanism is no longer
used by any package, remove it from the common infrastructure.

The latest user was nfs-utils, which used this mechanism to do the
"make install" as root, since doing otherwise was not supported. But
since 16e7b8255c, nfs-utils has been
upgraded and converted to the package infrastructure, and this hack is
no longer necessary. Another past user was the ltp-testsuite package,
for the same reason, and since
a72a670489, the fakeroot hack is no
longer needed.

13a3afc536 fs/initramfs: refactor with fs/cpio
An initramfs is in fact the same as a cpio archive, but embedded in
the kernel.  So instead of duplicating the cpio infrastructure,
we can simply build images/rootfs.cpio and link that into the

10a130f91e initramfs/init: make sure that 0, 1, 2 fds are available
As the kernel doesn't automatically mount devtmpfs when an initramfs
is used, commit 424888e474 has
introduced a small wrapper script that mounts devtmpfs before starting
the real init.

Unfortunately, the problem is that in this case, the init process runs
without any 0, 1 and 2 file descriptors, so none of the
messages/errors printed by the various initialization scripts can be
seen. This is due to the fact the init process relies on 0, 1 and 2
being opened by the kernel before init is started. However, as
/dev/console isn't present on the filesystem at the time the kernel
tries to open the console to create the 0, 1 and 2 file descriptors,
the kernel fails on this and prints the famous "Warning: unable to
open an initial console".

The proposed workaround is to actually open 0, 1 and 2 to /dev/console
in the wrapper script, right after mounting the devtmpfs filesystem,
and before starting the real init. The "Warning" from the kernel is
still shown, but at least the messages from the init scripts are
visible.

 - udev method selects udev for installation

All dynamic methods are based on devtmpfs, so one doesn't need to care
