Move boot media to /media/realroot for easy access after boot.

2014-07-10T16:37:39+00:00

There are cases where software after boot may need to know the
current boot disk.  Under the current system, it is not guaranteed
which disk is the boot.  While /media/sda is a good guess, it
isn't always right, nor is it a good assumption that only one boot
disk is in the system.  This gives a standard path to the original
boot disk mount which can be used to, for instance, update the
syslinux file on the boot media with a newer kernel, or updating
the boot parameters to add user options for future boots.  Knowing
which disk is the boot media keeps from updating the non-boot
disk when for instance multiple syslinux boot medias are plugged in
(ie ensure correct syslinux is updated when the booted system is
updated).

initrdscripts: Try to boot if boot label is unknown

2014-06-29T07:57:57+00:00

The init-live.sh scripts assumes that the boot label set by
the LABELS variable is either "boot", "install", or
"install-efi".  If that variable is overridden to something else
we fall off the end of the case statement and the system locks
up.  If the boot label is unknown, at least attempt to boot.

initrdscripts: fix for /run/media

2014-05-20T13:53:00+00:00

mount.sh in udev-extraconf was modified to use /run/media instead
of /media. Unfortunately, our scripts in initrdscripts have some
dependency on the auto-mounting mechanism proviced by udev-extraconf.
So these scripts should also be fixed to use /run/media instead /media,
otherwise, our live image cannot work correctly.

init-live.sh: list block devices correctly

2014-05-20T13:52:39+00:00

Instead of using 'ls /dev/sd*' command to list block devices, we
should rather use 'cat /proc/partitions'.

initrdscripts: add $CMDLINE to init-live switch_root

2014-01-16T12:03:14+00:00

init-live.sh: $CMDLINE variable should be provided to switch_root
to let user specify runlevel on grub command line.
Feeding with -c /dev/console as well as busybox switch_root enables that option.

init-live.sh: remove the '-c /dev/console' for switch_root

2013-12-05T13:30:20+00:00

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-live.sh: distinguish between a read-only image and a read-write image

2013-09-11T10:04:05+00:00

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.

init-live.sh: make $ROOT_MOUNT/media writable when necessary

2013-08-16T10:14:14+00:00

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.
