From: Chen Qi <qi.c...@windriver.com>
Previously, the boot action for live images was totally determined
by the LABEL value in the boot parameters (/proc/cmdline).
This behavior is not very convenient for users. The user may just want
to drop to a shell for troubleshooting the live image, or the user may
want to try to install the live image while the LABEL value is 'boot'.
We should provide the users a chance to choose the boot action when
the live image starts up.
This patch starts to implement this behavior by providing three choices
at boot time, 'boot', 'install' and 'shell'.
