I'd think ubifs is the FS of choice.... both Intel and Nokia experts are behind
that choice.
N900 has only 256MB of NAND flash which is kind of a bottleneck for a sane
rootfs + user apps. So we can use either emmc (some part of 32GB) or MMC card
(1GB+). and btrfs seems worth a try even on N900.
Most N900 users would want to preserve Maemo 5 rootfs (on NAND) and user content
on emmc while trying out/developing Meego, so MMC card seems to be the
preferable the medium for Meego rootfs as of today.
