[Yongqin Liu]

Updated according to the review comment.

This approach is actually a nice improvement from what we have now. Some
small comments:

Since this is an array, you should declare like:
   possible_partitions_files = schema.ListOption(default = [
       "init.partitions.rc", "fstab.partitions", "init.rc"])

Because of my change to config.py above the change to this file isn't
needed now.

due to the config.py change I suggested, you don't need to
"string_to_list" call now.

Why the conditional, seems like you should just print it out here and
then delete the call below that always tries to cat it?

Why are you keeping the call to "cat init.rc"?

I'm a little confused, isn't this something that is more likely to vary
by build than by target board?

Cheers,

Like the comment just above the condition,
Here is a modification about the PS1 below, so keep the condition there.
Now I deleted the condition by moving the PS1 modification before this

Yes, actually it varies by build, like ICS, JB, or others.
but will also varies by board because bhoj says that "we will be adding a cleanup to look at fstab.<ro.hardware> which would map to fstab.omap4pandaboard fstab.origen etc ."

and for us, we just need to list all the possible file there, and it will be OK I think.

i think its better than what we had in the first place
