Answering to myself:

chroot $chroot urpmi dracut
$chroot/usr/lib/dracut/modules.d/30convertfs/convertfs.sh $chroot

That did the conversion, but I still can't update, probably because my
rpm is too old (rpm-4.9.1.3-2.mga2) as it was not possible to update
it before the conversion (it pulls filesystem).
