The '-c DEV' option is specific to the switch_root provided by busybox.
switch_root from util-linux doesn't recognize this option. As a result,
if we we this init-live.sh script together with util-linux, we would get
a kernel panic when executing switch_root.
Besides, this option doesn't seem to have any useful effect as far as I
can see. Removing it doesn't affect the behaviours of our live images.

init-install.sh: remove unnecessary udev rules file to avoid error messages
/etc/udev/scripts/mount.sh is removed by init-install-efi.sh, but the
udev rules file which specifies the invocation of this script is not
removed, thus causing the error message during a live install:

The iso and hddimg share a common concept of 'live image', and they
use the same initramfs and thus the same init. However, that init
script in initramfs made a wrong assumption that the rootfs image
was read-only by itself. This is apparently not true for hddimg.
To make things work as expected, this init script should at least
distinguish between a read-only rootfs image and a read-write one.
This patch adds this ability to the init script. After this change,
the init script would be able to check whether the rootfs image is
read-only or not. If the rootfs image is read-write, the image will
be mounted and then booted directly. No union mounts will be attempted
in this case.

Previously, the boot partition was created for the target hard drive

even if the boot partition was mounted, it would just result in odd

Besides, for future maintance work, this patch also renames some of the
intermediate directories. It uses more descriptive names like /tgt_root
and /src_root. The name of /ssd is dropped.

If the live image is mounted as read-only, we cannot make necessary
directories under $ROOT_MOUNT/media, so trying to move the mount points
lead to errors.
So in case that no unification filesystem mechanism is available in kernel
and the rootfs is mounted as read-only, we mount tmpfs on $ROOT_MOUNT/media
so that it's possible to make necessary directories under it.

When boot media has been found, udev will be killed. If udev is busy
to mount other medias at the killing time (especially medias is many),
the above issue will occur occasionally.
Invoke `udevadm settle' before killing udev will resolve this
issue, it watches the udev event queue, and exits if all current
events are handled.
Use variable `_UDEV_DAEMON' to replace hardcoded `udevd' to keep
consistent with previous.

After a BSP board is booted with Yocto linux from USB drive, "cat /proc/mounts" shows:
...

/dev/sda2 /media/sda2 ext3 rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered 0 0
...
but actually the directory /media/sda1 doesn't exist at all, "df" shows:
...
df: /media/sda3: No such file or directory
df: /media/sda1: No such file or directory
df: /media/sda2: No such file or directory
...
2, This is because the mount data comes from proc setup during early boot
before the change root, which then uses a different root filesystem, the
media is not in the new root filesystem.
3, During early boot before switch_root, use `mount --move' to move all
medias to the new root filesystem could also fix this issue.

The install boot option was giving the following error when one tried to
install the live image on a permanent storage of a BSP.
cat: write error Invalid argument
Installation image failed
sh: can't access tty: job control turned off
Further digging into the issue, found out that the install script was trying
to do this:
cat /proc/mounts > /etc/mtab
And in the base-files recipe the /etc/mtab is made soft link to /proc/mounts.
So the cat command was failing to write on /etc/mtab. As the contents of
the /proc/mounts is already reflected in the /etc/mtab file due to the
symlink-ing, there is no need for this step to recreate /etc/mtab in the
install script. So just removing this unnecessary step, which solves the
install issue of the live images.
Fixes this bug:

Fixes [YOCTO #3870] atom-pc - cannot boot image on netbook after install
The problem here is that grub2 is installed but a grub 1 menu.lst is
created at install time. At boot, grub2 doesn't find a grub.cfg file and
drops to the grub shell.
This happens because the installer is looking for 40_custom (a grub2
file) on the rootfs, but grub2 isn't installed on the rootfs. It exists
in the initramfs. Patching the installer to look on the initramfs
resolves the problem.
Note that the problem may have occurred if grub2 used to be installed on
the rootfs but was later removed. In any case, the installer is HORRIBLE
and really needs to be completely redesigned as part of the deployment
effort. For now, this should get the live image installer limping along
again.

start and end positions of the same value. This avoids the 1 MB gaps.
Rather than pad the disk with 1MB in the beginning and cut it off at the
MB boundary on the end, we can use 0% and 100% to allow parted to do the
required math and use as much of the disk as possible.

We create both the boot and root partitions as ext3 now, update the
logging accordingly.

swap_size currently uses a hard coded percentage and ignores the
swap_ratio variable. Fortunately they are the same value currently. Make
the calculation use the variable to avoid problems in the future.

Fixes [YOCTO #2385]
The installer only searches for hd[ab] sd[ab]. Some newer BSPs have mmcblk
devices that should be used as the install target. These devices also have a
partition prefix (mmcblk0p1 instead of mmcblk01). As they are detected
asynchronously, it is necessary to add the rootwait kernel parameter to avoid
a race condition trying to mount the root device.
As BSPs like the FRI2 and the sys940x have mmc devices and will have a 1.2
release, we should push this to 1.2.1. The changes are perfectly contained and
easily verified.
Test for an mmcblk device and add the p partition prefix if necessary. Add the
rootwait kernel parameter when an mmcblk device is detected. Replace the series
of explicit umount commands with a single umount using a wildcard. This will
find all the partitions and will not try to unmount non-existant devices. Avoid
copy and paste errors by replacing /dev/${device}${pX} references with the
previously assigned rootfs, bootfs, and swap variables.
These changes have been tested on the FRI2 Sato image which installed to
/dev/mmcblk0 as well as the N450 Sato image which installed to /dev/sda. Both
were successful.

There are issues with the current unionfs when making a union mount over "/".
Until these are resolved we can't use unionfs for live booting so disable this
temporarily as a workaround.
unionfs is usable in other circumstances.

[YOCTO #1487]
When booting up with liveCD image, init scripts can't work well on read-only filesystem. Unionfs,
which is supported in Yocto kernel, allows a filesystem to appear as writeable, but without
actually allowing writes to change the filesystem.
Use unionfs to mount rootfs and make root file system can be writen when using liveCD to boot up.
Set UNION_FS variable depending on kernel config, so that it can work with kernel which doesn't
have unionfs feature.

The script was making some assumptions that enforced many requirement
in the machine kernel configuration and usage, besides it were too
while booting.
Changes included:
* fix indentation;
* rdepends on udev;
* allow use of isofs as module;
* remove rootdelay param parsing as it was unused;
* don't verbosely kill udevd and mknod;
* mount devtmpfs into rootfs, if available, before swithing root;
