Qi.Chen@windriver.com - Dec. 31, 2012, 2:16 a.m.
From: Chen Qi <Qi.Chen@windriver.com>

To support a read-only rootfs, we use symbolic links which point
to volatile storage to create the illusion that some directories
are writable.

Improve populate-volatile.sh script to support read-only rootfs.
Add two default config files specific to read-only-rootfs image.

Good.

I'd prefer it to be in another package.

Why a specific readonly file?

Couldn't it be done using a 01_sato_readonly? for example?
