2c8502e821 /etc/profile: read in /etc/profile.d/*.sh files
For custom projects, it is more maintainable to add custom profile settings
in a separate file, than directly in /etc/profile.

This patch modifies /etc/profile to read in *.sh files from /etc/profile.d/,
a technique commonly used in Linux distributions.

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
kernel.

3fac21ef8d cpio: fix boot with dynamic /dev
Devtmpfs doesn't get automounted by the kernel when an initramfs is used.
Since cpio archives are used almost exclusively as an initramfs, the same
fix should be applied to it as for the initramfs.

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.

9dc7b73f3b System config: split static-dev device table setting into seperate option
As discussed here:

http://lists.busybox.net/pipermail/buildroot/2011-May/043251.html

Add BR2_ROOTFS_STATIC_DEVICE_TABLE for the extra device table file(s)
to create device nodes in /dev, rather than complicated logic in
BR2_ROOTFS_DEVICE_TABLE, making it complicated to move between static
and dynamic modes.

424888e474 initramfs: fix boot with dynamic /dev
Devtmpfs (which is used by devtmpfs/mdev/udev options) doesn't get
automounted by the kernel when an initramfs is used, causing boot
failures when a dynamic /dev is used.

Fix it by adding a pre-init script to mount devtmpfs before running init.

726b15f64a Create menu entry to select device creation method
Four methods for the creation of device files in /dev are now
proposed:

 - static method uses device table as before
 - devtmpfs method enables this feature in kernel
 - mdev method adds mdev starting script to the file system
    and selects mdev itself for installation
 - udev method selects udev for installation

All dynamic methods are based on devtmpfs, so one doesn't need to care
about /dev folder.
