I proposed that a long time ago on this list and i created images with
BTRFS of the Common profile.
It works however i got a lot of data corruption situations during power
losses, the BTRFS has to be tuned specifically for the mobile device world.
Also there is a "new" project for eMMC devices called vdfs, i don't know
any details of it but it's there: http://sourceforge.net/projects/vdfs/

we are dealing with embedded which has a lot of constrains when it come

Tizen request is so far only to provide a file system with extended
attribute support to store Smack labels.
Each profiles has its own constrains from persistence to support of very
low cost NAND and they can select the best file system for their need.
Then the responsibility of configuring system to withstand power
losses and such in regards to system state is up to whoever selects
the filesystem. IOW, state management regarding user management is not
an issue. That also means that scripts are completely fine.
IMO, we should generate our images using Btrfs instead of ext4.
