Hi Otavio:
V6 has been sent with support for customized conf files.
Also, the specific conf files are provided by corresponding image
recipes, because the contents of the conf files are closely related to
the image types.
Cheers,
Chen Qi

read_only_rootfs_hook: this funtion is invoked only if 'read-only-rootfs'
is in IMAGE_FEATURES. It tweaks some basic files and makes populate-
volatile.sh script run at rootfs time.
choose_volatile_conf_file: this function is invoked no matter
'read-only-rootfs' is in IMAGE_FEATURES or not, it properly chooses
the right conf file for volatile storage handling according to the
IMAGE_FEATURES.

Wouldn't be better to have a package which provides the need valatile
config? this makes it easy to reuse for other images.
